2018-08-27ALSA: hdspm: fix spelling mistake "Initializeing" -> "Initializing"Colin Ian King1-1/+1
Trivial fix to spelling mistake in dev_dbg message and also remove extraneous white space and repeated question marks. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-04-25ALSA: hdspm: Hardening for potential Spectre v1Takashi Iwai1-10/+14
As recently Smatch suggested, a couple of places in HDSP MADI driver may expand the array directly from the user-space value with speculation: sound/pci/rme9652/hdspm.c:5717 snd_hdspm_channel_info() warn: potential spectre issue 'hdspm->channel_map_out' (local cap) sound/pci/rme9652/hdspm.c:5734 snd_hdspm_channel_info() warn: potential spectre issue 'hdspm->channel_map_in' (local cap) This patch puts array_index_nospec() for hardening against them.

2017-10-26ALSA: Convert timers to use timer_setup()Kees Cook1-4/+4
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. These are all the "mechanical" changes remaining in the sound subsystem.

2017-09-07ALSA: hdspm: Use common error handling code in snd_hdspm_probe()Markus Elfring1-8/+8
Add a jump target so that a bit of exception handling can be better reused at the end of this function. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-08-12ALSA: rme9652: Adjust seven checks for null pointersMarkus Elfring1-9/+9

2017-08-12ALSA: rme9652: Improve eight size determinationsMarkus Elfring1-10/+8
Replace the specification of data structures by variable references as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention.

2017-08-12ALSA: rme9652: Delete an error message for a failed memory allocation in ↵Markus Elfring1-5/+1

2017-07-18ALSA: rme9652: fix format overflow warningsArnd Bergmann1-20/+28
gcc-7 warns about a possible sprintf format string overflow with a temporary buffer that is used to print from another buffer of the same size: sound/pci/rme9652/hdspm.c: In function 'snd_hdspm_create_alsa_devices': sound/pci/rme9652/hdspm.c:2123:17: error: ' MIDIoverMADI' directive writing 13 bytes into a region of size between 1 and 32 [-Werror=format-overflow=] This extends the temporary buffer to twice the size, and changes the code to use the safer snprintf() across the entire file. The longer buffer is still necessary to avoid a format-truncation warning. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-06-09ALSA: hdspm: Constify hw_constraintsTakashi Iwai1-2/+2
snd_pcm_hw_constraint_list(), *_ratnums() and *_ratdens() receive the const pointers. Constify the corresponding static objects for better hardening. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-01-12ALSA: pci: Constify snd_rawmidi_opsTakashi Iwai1-2/+2

2016-09-02ALSA: constify snd_pcm_ops structuresJulia Lawall1-1/+1
Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct snd_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2016-02-29ALSA: hdspm: Fix zero-divisionTakashi Iwai1-0/+8
HDSPM driver contains a code issuing zero-division potentially in system sample rate ctl code. This patch fixes it by not processing a zero or invalid rate value as a divisor, as well as excluding the invalid value to be passed via the given ctl element. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-02-29ALSA: hdspm: Fix wrong boolean ctl value accessesTakashi Iwai1-4/+4
snd-hdspm driver accesses enum item values (int) instead of boolean values (long) wrongly for some ctl elements. This patch fixes them. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-10-21ALSA: rme9652: Use snd_pcm_hw_constraint_single()Lars-Peter Clausen1-5/+4
Use the new snd_pcm_hw_constraint_single() helper function instead of calling snd_pcm_hw_constraint_minmax() with the same value for min and max to install a constraint that limits the possible configuration values to a single value. Using snd_pcm_hw_constraint_single() makes the indented result clearer. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-02-13ALSA: hdspm - Constrain periods to 2 on older cardsAdrian Knoth1-0/+6
RME RayDAT and AIO use a fixed buffer size of 16384 samples. With period sizes of 32-4096, this translates to 4-512 periods. The older RME cards have a variable buffer size but require exactly two periods. This patch enforces nperiods=2 on those cards.

2015-01-04ALSA: Deletion of checks before the function call "iounmap"Markus Elfring1-3/+1

2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine1-1/+1
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2013-08-19ALSA: hdspm - Fix default value in SNDRV_HDSPM_IOCTL_GET_LTCAdrian Knoth1-1/+1
Use enum hdspm_ltc_format's fps_30 (corresponds to 4) instead of 30, Other case branches return 1, 2 or 3 respectively, so 30 obviously is wrong. Since SNDRV_HDSPM_IOCTL_GET_LTC had never been working due to a copy&paste error in hdspm.h, this change doesn't break userspace.

2013-07-05ALSA: hdspm - AES32: Ignore float/int format bitAdrian Knoth1-0/+10
As mentioned in the comment, the AES32 cards must not set the format bit, since it is used to indicate the preferred sync setting instead.
