| * | | | media: imx-csi: fix burst sizeRussell King2017-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting a burst size of "8" doesn't work for IMX219 with 8-bit bayer, but a burst size of "16" does. Fix this. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Acked-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The complete handler walks all entities, expecting to find an imx subdevice for each and every entity. However, camera drivers such as smiapp can themselves contain multiple entities, for which there will not be an imx subdevice. This causes imx_media_find_subdev_by_sd() to fail, making the imx capture system unusable with such cameras. Work around this by killing the error entirely, thereby allowing the imx capture to be used with such cameras.

| * | | | media: staging: imx: use ktime_t for timestampsArnd Bergmann2017-12-083-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The imx media driver passes around monotonic timestamps in the deprecated 'timespec' format. This is not a problem for the driver, as they won't overflow, but moving to either timespec64 or ktime_t is preferred. I'm picking ktime_t for simplicity here. frame_interval_monitor() is the main function that changes, as it tries to compare a time interval in microseconds. The algorithm slightly changes here, to avoid 64-bit division. The code previously assumed that the error was at most 32-bit worth of microseconds here, so I'm making the same assumption but add an explicit test for it.

In this case the vb2_queue state will be set to streaming but the start_streaming vb2_op will not be called. Later when enough buffers are queued, start_streaming will be called but vb2_is_streaming will already return true. Also removed the queue state check in stop_streaming since it's not valid there either.

Summary: - add checks for mistakes, like the choice default is not in choice, help is doubled - document data structure and complex code - fix various memory leaks - change Makefile to build lexer and parser instead of using pre-generated C files - drop 'boolean' keyword, which is equivalent to 'bool' - use default 'yy' prefix and remove unneeded Make variables - fix gettext() check for xconfig - announce that oldnoconfig will be finally removed - make 'Selected by:' and 'Implied by' readable in help and search result - hide silentoldconfig from 'make help' to stop confusing people - fix misc things and cleanups" * tag 'kconfig-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (37 commits) kconfig: Remove silentoldconfig from help and docs; fix kconfig/conf's help kconfig: make "Selected by:" and "Implied by:" readable kconfig: announce removal of oldnoconfig if used kconfig: fix make xconfig when gettext is missing kconfig: Clarify menu and 'if' dependency propagation kconfig: Document 'if' flattening logic kconfig: Clarify choice dependency propagation kconfig: Document SYMBOL_OPTIONAL logic kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX kconfig: use default 'yy' prefix for lexer and parser kconfig: make conf_unsaved a local variable of conf_read() kconfig: make xfgets() really static kconfig: make input_mode static kconfig: Warn if there is more than one help text kconfig: drop 'boolean' keyword kconfig: use bool instead of boolean for type definition attributes, again kconfig: Remove menu_end_entry() kconfig: Document important expression functions kconfig: Document automatic submenu creation code kconfig: Fix choice symbol expression leak ...

But this hunk of code was dropped from original commit. As result the logic works wrong and current code use struct kib_conn after free. > drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c > 3317 kiblnd_destroy_conn(conn, !peer); > ^^^^ Freed always (but should be conditionally) > 3318 > 3319 spin_lock_irqsave(lock, flags); > 3320 if (!peer) > 3321 continue; > 3322 > 3323 conn->ibc_peer = peer; > ^^^^^^^^^^^^^^ Use after free > 3324 if (peer->ibp_reconnected < KIB_RECONN_HIGH_RACE) > 3325 list_add_tail(&conn->ibc_list, > ^^^^^^^^^^^^^^ Use after free > 3326 &kiblnd_data.kib_reconn_list); > 3327 else > 3328 list_add_tail(&conn->ibc_list, > ^^^^^^^^^^^^^^ Use after free > 3329 &kiblnd_data.kib_reconn_wait); To avoid confusion this fix moved the freeing a struct kib_conn outside of the function kiblnd_destroy_conn() and free as it was intended in original commit.

Also avoid the #ifdef by allocating a cpumask_var and copying into it, rather than sharing the mask.

That means that when we try to calculate "ms_card->total_block / 512 - 1" then it's just always -1. The fix is to calculate "seg_no" before doing the memset(). This is a static checker fix, and I am not able to test it. My theory is that reset_ms_card() gets very little testing which is why this bug exists.
