2009-11-09pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (char)Dominik Brodowski1-25/+17
Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of requiring manual settings of PCMCIA_DEBUG. Only some rare extra debug checks in cm4000_cs.c cm4040_cs.c are now hidden behind a "#ifdef CM4000_DEBUG" or "#ifdef CM4040_DEBUG". Also, remove all usages of the CS_CHECK macro and replace them with proper Linux style calling and return value checking. The extra error reporting may be dropped, as the PCMCIA core already complains about any (non-driver-author) errors.

2008-10-16device create: char: convert device_create_drvdata to device_createGreg Kroah-Hartman1-2/+1
Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-08-23pcmcia: deprecate CS_SUCCESSDominik Brodowski1-2/+2
Instead of using own error or success codes, the PCMCIA code should rely on the generic return values. Therefore, replace all occurrences of CS_SUCCESS with 0. CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: pcmcia_config_loop() improvement by passing vccDominik Brodowski1-0/+1
By passing the current Vcc setting to the pcmcia_config_loop callback function, we can remove pcmcia_get_configuration_info() calls from many drivers. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: pcmcia_config_loop() default CIS entry handlingDominik Brodowski1-0/+1
Many drivers use the default CIS entry within their pcmcia_config_loop() callback function. Therefore, factor the default CIS entry handling out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2008-08-23pcmcia: pcmcia_config_loop() ConfigIndex unificationDominik Brodowski1-2/+0
Almost all drivers set p_dev->conf.ConfigIndex to cfg->index in the pcmcia_config_loop() callback function. Therefore, factor it out. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2007-11-14cm40x0_cs.c: fix debug macrosPascal Terjan1-1/+1
When PCMCIA_DEBUG is set, cm40x0_cs.c and cm4000_cs.c don't build because the definition of reader_to_dev uses a non-existent handle field of the struct pcmcia_device in the call to handle_to_dev. As handle_to_dev works on struct pcmcia_device, the fix is quite trivial.

2007-03-06[PATCH] Fix buffer overflow in Omnikey CardMan 4040 driver (CVE-2007-0005)Marcel Holtmann1-1/+2
Based on a patch from Don Howard <dhoward@redhat.com> When calling write() with a buffer larger than 512 bytes, the driver's write buffer overflows, allowing to overwrite the EIP and execute arbitrary code with kernel privileges. In read(), there exists a similar problem, but coming from the device. A malicous or buggy device sending more than 512 bytes can overflow of the driver's read buffer, with the same effects as above.

- Use timer macros to set function and data members and to modify expiration time. - Use DEFINE_TIMER for global timers and do not init them at run-time in these cases. - del_timer_sync is common in most cases -- we want to wait for timer function if it's still running.

2006-12-04[PATCH] pcmcia: conf.ConfigBase and conf.Present consolidationDominik Brodowski1-20/+0
struct pcmcia_device *p_dev->conf.ConfigBase and .Present are set in almost all PCMICA driver right at the beginning, using the same calls but slightly different implementations.

2006-12-04[PATCH] cm4000_cs: fix return value checkAkinobu Mita1-3/+3

2006-07-03[PATCH] make more file_operation structs staticArjan van de Ven1-1/+1
Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..

2006-03-31[PATCH] pcmcia: convert DEV_OK to pcmcia_dev_presentDominik Brodowski1-1/+1

2006-03-31[PATCH] pcmcia: use bitfield instead of p_state and stateDominik Brodowski1-12/+4
Instead of the two status values struct pcmcia_device->p_state and state, use descriptive bitfields. Most value-checking in drivers was invalid, as the core now only calls the ->remove() (a.k.a. detach) function in case the attachement _and_ configuration was successful.

2006-03-31[PATCH] pcmcia: add return value to _config() functionsDominik Brodowski1-6/+9
Most of the driver initialization isn't done in the .probe function, but in the internal _config() functions. Make them return a value, so that .probe can properly report whether the probing of the device succeeded or not. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-03-31[PATCH] pcmcia: remove dev_link_t and client_handle_t indirectionDominik Brodowski1-29/+24

2006-03-31[PATCH] pcmcia: embed dev_link_t into struct pcmcia_deviceDominik Brodowski1-16/+13

2006-03-31[PATCH] pcmcia: remove unneeded Vcc pseudo settingDominik Brodowski1-7/+0

2006-03-31[PATCH] pcmcia: default suspend and resume handlingDominik Brodowski1-24/+0

2006-03-31[PATCH] pcmcia: add pcmcia_disable_deviceDominik Brodowski1-2/+1
pcmcia_disable_device(struct pcmcia_device *p_dev) performs the necessary cleanups upon device or driver removal: it calls the appropriate pcmcia_release_* functions, and can replace (most) of the current drivers' _release() functions. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2006-01-06[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski1-56/+11
callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-01-06[PATCH] pcmcia: unify detach, REMOVAL_EVENT handlers into one remove callbackDominik Brodowski1-35/+17

2006-01-05[PATCH] pcmcia: new suspend coreDominik Brodowski1-25/+25
Move the suspend and resume methods out of the event handler, and into special functions.
