2013-03-18mac80211: move sdata debugfs dir to vifStanislaw Gruszka1-5/+5
There is need create driver own per interface debugfs files. This is currently done by drv_{add,remove}_interface_debugfs() callbacks. But it is possible that after we remove interface from the driver (i.e. on suspend) we call drv_remove_interface_debugfs() function. Fixing this problem will require to add call drv_{add,remove}_interface_debugfs() anytime we create and remove interface in mac80211. So it's better to add debugfs dir dentry to vif structure to allow to create/remove custom debugfs driver files on drv_{add,remove}_interface().

2012-07-06mac80211: fix debugfs default key linksJohannes Berg1-6/+10
Due to the way the default key links are created, it happens that a link is left dangling: * both unicast/multicast links are created * unicast link is destroyed, and the links are updated * during this update, adding the multicast link again fails because it is present, destroying the debugfs pointer * removing the multicast link won't work as the pointer has been destroyed Fix this by always removing the links and then re-creating them if needed.

2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd1-2/+2
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-07-08mac80211: fix CCMP racesJohannes Berg1-2/+4
Since we can process multiple packets at the same time for different ACs, but the PN is allocated from a single counter, we need to use an atomic value there. Use atomic64_t to make this cheaper on 64-bit platforms, other platforms will support this through software emulation, see lib/atomic64.c. We also need to use an on-stack scratch buf so that multiple packets won't corrupt each others scratch buffers. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-05-16mac80211: sparse RCU annotationsJohannes Berg1-12/+9
This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-10-29mac80211: fix failure to check kmalloc return value in key_key_readJesper Juhl1-1/+5
I noticed two small issues in mac80211/debugfs_key.c::key_key_read while reading through the code. Patch below. The key_key_read() function returns ssize_t and the value that's actually returned is the return value of simple_read_from_buffer() which also returns ssize_t, so let's hold the return value in a ssize_t local variable rather than a int one. Also, memory is allocated dynamically with kmalloc() which can fail, but the return value of kmalloc() is not checked, so we may end up operating on a null pointer further on. So check for a NULL return and bail out with -ENOMEM in that case. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-09-16net/wireless: use generic_file_llseek in debugfsArnd Bergmann1-0/+2
The default llseek operation is changing from default_llseek to no_llseek, so all code relying on the current behaviour needs to make that explicit. The wireless driver infrastructure and some of the drivers make use of generated debugfs files, so they cannot be converted by our script that automatically determines the right operation. All these files use debugfs and they typically rely on simple_read_from_buffer, so the best llseek operation here is generic_file_llseek. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: "John W.

2010-06-15mac80211: Use a separate CCMP PN receive counter for management framesJouni Malinen1-1/+1
When management frame protection (IEEE 802.11w) is used, we must use a separate counter for tracking received CCMP packet number for the management frames. The previously used NUM_RX_DATA_QUEUESth queue was shared with data frames when QoS was not used and that can cause problems in detecting replays incorrectly for robust management frames. Add a new counter just for robust management frames to avoid this issue. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2009-12-21mac80211: reduce reliance on netdevJohannes Berg1-1/+1
For bluetooth 3, we will most likely not have a netdev for a virtual interface (sdata), so prepare for that by reducing the reliance on having a netdev. This patch moves the name and address fields into the sdata struct and uses them from there all over. Some work is needed to keep them sync'ed, but that's not a lot of work and in slow paths anyway. In doing so, this also reduces the number of pointer dereferences in many places, because of things like sdata->dev->dev_addr becoming sdata->vif.addr.

2009-10-30cfg80211/mac80211: use debugfs_remove_recursiveJohannes Berg1-31/+13
We can save a lot of code and pointers in the structs by using debugfs_remove_recursive(). First, change cfg80211 to use debugfs_remove_recursive() so that drivers do not need to clean up any files they added to the per-wiphy debugfs (if and only if they are ok to be accessed until after wiphy_unregister!). Then also make mac80211 use debugfs_remove_recursive() where necessary -- it need not remove per-wiphy files as cfg80211 now removes those, but netdev etc. files still need to be handled but can now be removed without needing struct dentry pointers to all of them.

2008-09-02mac80211: Fix debugfs union misuse and pointer corruptionJouni Malinen1-3/+3
debugfs union in struct ieee80211_sub_if_data is misused by including a common default_key dentry as a union member. This ends occupying the same memory area with the first dentry in other union members (structures; usually drop_unencrypted). Consequently, debugfs operations on default_key symlinks and drop_unencrypted entry are using the same dentry pointer even though they are supposed to be separate ones. This can lead to removing entries incorrectly or potentially leaving something behind since one of the dentry pointers gets lost. Fix this by moving the default_key dentry to a new struct (common_debugfs) that contains dentries (more to be added in future) that are shared by all vif types. The debugfs union must only be used for vif type-specific entries to avoid this type of pointer corruption.

2008-04-08mac80211: fix key vs. sta locking problemsJohannes Berg1-19/+18
Up to now, key manipulation is supposed to run under RTNL to avoid concurrent manipulations and also allow the set_key() hardware callback to sleep. This is not feasible because STA structs are rcu-protected and thus a lot of operations there cannot take the RTNL. Also, key references are rcu-protected so we cannot do things atomically. This patch changes key locking completely: * key operations are now atomic * hardware crypto offload is enabled and disabled from a workqueue, due to that key freeing is also delayed * debugfs code is also run from a workqueue * keys reference STAs (and vice versa!) so during STA unlink the STAs key reference is removed but not the keys STA reference, to avoid races key todo work is run before STA destruction. * fewer STA operations now need the RTNL which was required due to key operations This fixes the locking problems lockdep pointed out and also makes things more light-weight because the rtnl isn't required as much. Note that the key todo lock/key mutex are global locks, this is not required, of course, they could be per-hardware instead.

2007-10-10[MAC80211]: rework key handlingJohannes Berg1-2/+2
This moves all the key handling code out from ieee80211_ioctl.c into key.c and also does the following changes including documentation updates in mac80211.h: 1) Turn off hardware acceleration for keys when the interface is down. This is necessary because otherwise monitor interfaces could be decrypting frames for other interfaces that are down at the moment. Also, it should go some way towards better suspend/resume support, in any case the routines used here could be used for that as well. Additionally, this makes the driver interface nicer, keys for a specific local MAC address are only ever present while an interface with that MAC address is enabled. 2) Change driver set_key() callback interface to allow only return values of -ENOSPC, -EOPNOTSUPP and 0, warn on all other return values. This allows debugging the stack when a driver notices it's handed a key while it is down. 3) Invert the flag meaning to KEY_FLAG_UPLOADED_TO_HARDWARE. 4) Remove REMOVE_ALL_KEYS command as it isn't used nor do we want to use it, we'll use DISABLE_KEY for each key. It is hard to use REMOVE_ALL_KEYS because we can handle multiple virtual interfaces with different key configuration, so we'd have to keep track of a lot of state for this and that isn't worth it. 5) Warn when disabling a key fails, it musn't. 6) Remove IEEE80211_HW_NO_TKIP_WMM_HWACCEL in favour of per-key IEEE80211_KEY_FLAG_WMM_STA to let driver sort it out itself. 7) Tell driver that a (non-WEP) key is used only for transmission by using an all-zeroes station MAC address when configuring. 8) Change the set_key() callback to have access to the local MAC address the key is being added for.

2007-10-10[MAC80211]: embed key conf in key, fix driver interfaceJohannes Berg1-17/+32
This patch embeds the struct ieee80211_key_conf into struct ieee80211_key and thus avoids allocations and having data present twice. This required some more changes: 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag. This flag isn't used by drivers nor should it be since we have a set_key_idx() callback. Maybe that callback needs to be extended to include the key conf, but only a driver that requires it will tell. 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag. This flag is global, so it shouldn't be passed in the key conf structure. Pass it to the function instead. Also, this patch removes the AID parameter to the set_key() callback because it is currently unused and the hardware currently cannot know about the AID anyway. I suspect this was used with some hardware that actually selected the AID itself, but that functionality was removed. Additionally, I've removed the ALG_NULL key algorithm since we have ALG_NONE.
