commit 5e47f198 upstream. This patch fixes an active I/O shutdown bug for fabric drivers using target_wait_for_sess_cmds(), where se_cmd descriptor shutdown would result in hung tasks waiting indefinitely for se_cmd->cmd_wait_comp to complete(). To address this bug, drop the incorrect list_del_init() usage in target_wait_for_sess_cmds() and always complete() during se_cmd target_release_cmd_kref() put, in order to let caller invoke the final fabric release callback into se_cmd->se_tfo->release_cmd() code.

commit c8b08ca5 upstream. mkspec is copying built kernel to temporrary location /boot/vmlinuz-$KERNELRELEASE-rpm and runs installkernel on it. This however directly leads to grub2 menuentry for this suffixed binary being generated as well during the run of installkernel script. Later in the process the temporary -rpm suffixed files are removed, and therefore we end up with spurious (and non-functional) grub2 menu entries for each installed kernel RPM. Fix that by using a different temporary name (prefixed by '.'), so that the binary is not recognized as an actual kernel binary and no menuentry is created for it. Signed-off-by:

commit 3debb0a9 upstream. The trace_printk() code will allocate extra buffers if the compile detects that a trace_printk() is used. To do this, the format of the trace_printk() is saved to the __trace_printk_fmt section, and if that section is bigger than zero, the buffers are allocated (along with a message that this has happened). If trace_printk() uses a format that is not a constant, and thus something not guaranteed to be around when the print happens, the compiler optimizes the fmt out, as it is not used, and the __trace_printk_fmt section is not filled. This means the kernel will not allocate the special buffers needed for the trace_printk() and the trace_printk() will not write anything to the tracing buffer. Adding a "__used" to the variable in the __trace_printk_fmt section will keep it around, even though it is set to NULL. This will keep the string from being printed in the debugfs/tracing/printk_formats section as it is not needed. Reported-by:

commit a29054d9 upstream. If tracing contains data and the trace_pipe file is read with sendfile(), then it can trigger a NULL pointer dereference and various BUG_ON within the VM code. There's a patch to fix this in the splice_to_pipe() code, but it's also a good idea to not let that happen from trace_pipe either.

commit cb86e053 upstream. Joel Fernandes reported that the function tracing of preempt disabled sections was not being reported when running either the preemptirqsoff or preemptoff tracers. This was due to the fact that the function tracer callback for those tracers checked if irqs were disabled before tracing. But this fails when we want to trace preempt off locations as well. Joel explained that he wanted to see funcitons where interrupts are enabled but preemption was disabled. The expected output he wanted: <...>-2265 1d.h1 3419us : preempt_count_sub <-irq_exit <...>-2265 1d..1 3419us : __do_softirq <-irq_exit <...>-2265 1d..1 3419us : msecs_to_jiffies <-__do_softirq <...>-2265 1d..1 3420us : irqtime_account_irq <-__do_softirq <...>-2265 1d..1 3420us : __local_bh_disable_ip <-__do_softirq <...>-2265 1..s1 3421us : run_timer_softirq <-__do_softirq <...>-2265 1..s1 3421us : hrtimer_run_pending <-run_timer_softirq <...>-2265 1..s1 3421us : _raw_spin_lock_irq <-run_timer_softirq <...>-2265 1d.s1 3422us : preempt_count_add <-_raw_spin_lock_irq <...>-2265 1d.s2 3422us : _raw_spin_unlock_irq <-run_timer_softirq <...>-2265 1..s2 3422us : preempt_count_sub <-_raw_spin_unlock_irq <...>-2265 1..s1 3423us : rcu_bh_qs <-__do_softirq <...>-2265 1d.s1 3423us : irqtime_account_irq <-__do_softirq <...>-2265 1d.s1 3423us : __local_bh_enable <-__do_softirq There's a comment saying that the irq disabled check is because there's a possible race that tracing_cpu may be set when the function is executed. But I don't remember that race. For now, I added a check for preemption being enabled too to not record the function, as there would be no race if that was the case. I need to re-investigate this, as I'm now thinking that the tracing_cpu will always be correct. But no harm in keeping the check for now, except for the slight performance hit.

commit 459ee1c3 upstream. As observed on Apple iMac10,1, DCE-3.2, RV-730, link rate of 2.7 Ghz is not selected, because the args.v1.ucConfig flag setting for 2.7 Ghz gets overwritten by a following assignment of the transmitter to use. Move link rate setup a few lines down to fix this. In practice this didn't have any positive or negative effect on display setup on the tested iMac10,1 so i don't know if backporting to stable makes sense or not. Signed-off-by:

commit 21b81716 upstream. Commit d63c7dd5 ("ipr: Fix out-of-bounds null overwrite") removed the end of line handling when storing the update_fw sysfs attribute. This changed the userpace API because it started refusing writes terminated by a line feed, which broke the update tools we already have. This patch re-adds that handling, so both a write terminated by a line feed or not can make it through with the update. Fixes: d63c7dd5 ("ipr: Fix out-of-bounds null overwrite") Signed-off-by:

commit d63c7dd5 upstream. Return value of snprintf is not bound by size value, 2nd argument. (https://www.kernel.org/doc/htmldocs/kernel-api/API-snprintf.html). Return value is number of printed chars, can be larger than 2nd argument. Therefore, it can write null byte out of bounds ofbuffer. Since snprintf puts null, it does not need to put additional null byte. Signed-off-by:

commit 378c6520 upstream. This commit fixes the following security hole affecting systems where all of the following conditions are fulfilled: - The fs.suid_dumpable sysctl is set to 2. - The kernel.core_pattern sysctl's value starts with "/". (Systems where kernel.core_pattern starts with "|/" are not affected.) - Unprivileged user namespace creation is permitted. (This is true on Linux >=3.8, but some distributions disallow it by default using a distro patch.) Under these conditions, if a program executes under secure exec rules, causing it to run with the SUID_DUMP_ROOT flag, then unshares its user namespace, changes its root directory and crashes, the coredump will be written using fsuid=0 and a path derived from kernel.core_pattern - but this path is interpreted relative to the root directory of the process, allowing the attacker to control where a coredump will be written with root privileges. To fix the security issue, always interpret core_pattern for dumps that are written under SUID_DUMP_ROOT relative to the root directory of init. Signed-off-by:

commit fafcde3a upstream. Inside multipath_make_request(), multipath maps the incoming bio into low level device's bio, but it is totally wrong to copy the bio into mapped bio via '*mapped_bio = *bio'. For example, .__bi_remaining is kept in the copy, especially if the incoming bio is chained to via bio splitting, so .bi_end_io can't be called for the mapped bio at all in the completing path in this kind of situation. This patch fixes the issue by using clone style. Reported-and-tested-by:

commit d6785d91 upstream.

commit c0a2ad9b upstream. On umount path, jbd2_journal_destroy() writes latest transaction ID (->j_tail_sequence) to be used at next mount. The bug is that ->j_tail_sequence is not holding latest transaction ID in some cases. So, at next mount, there is chance to conflict with remaining (not overwritten yet) transactions. mount (id=10) write transaction (id=11) write transaction (id=12) umount (id=10) <= the bug doesn't write latest ID mount (id=10) write transaction (id=11) crash mount [recovery process] transaction (id=11) transaction (id=12) <= valid transaction ID, but old commit must not replay Like above, this bug become the cause of recovery failure, or FS corruption. So why ->j_tail_sequence doesn't point latest ID? Because if checkpoint transactions was reclaimed by memory pressure (i.e. bdev_try_to_free_page()), then ->j_tail_sequence is not updated. (And another case is, __jbd2_journal_clean_checkpoint_list() is called with empty transaction.) So in above cases, ->j_tail_sequence is not pointing latest transaction ID at umount path. Plus, REQ_FLUSH for checkpoint is not done too. So, to fix this problem with minimum changes, this patch updates ->j_tail_sequence, and issue REQ_FLUSH. (With more complex changes, some optimizations would be possible to avoid unnecessary REQ_FLUSH for example though.) BTW, journal->j_tail_sequence = ++journal->j_transaction_sequence; Increment of ->j_transaction_sequence seems to be unnecessary, but ext3 does this. Signed-off-by:

commit 1f7c6658 upstream. Cirrus HD-audio driver may adjust GPIO pins for EAPD dynamically depending on the jack plug state. This works fine for the auto-mute mode where the speaker gets muted upon the HP jack plug. OTOH, when the auto-mute mode is off, this turns off the EAPD unexpectedly depending on the jack state, which results in the silent speaker output. This patch fixes the silent speaker output issue by setting GPIO bits constantly when the auto-mute mode is off. Reported-and-tested-by: moosotc@gmail.com Signed-off-by:

commit 5c915c68 upstream. On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max size results in a solid green rectangle being captured (all colors 0 in YUV). This turns out to be caused by max-width (924) not being a multiple of 16. We've likely never hit this problem before since normally xawtv / tvtime, etc. will prefer packed pixel formats. But when using a video card which is using xf86-video-modesetting + glamor, only planar XVideo fmts are available, and xawtv will chose a matching capture format to avoid needing to do conversion, triggering the solid green window problem.

commit 836b34a9 upstream. create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it. Based on a patch by Takashi Iwai <tiwai@suse.de> [Note for stable backports: this patch requires the commit 902eb7fd ('ALSA: usb-audio: Minor code cleanup in create_fixed_stream_quirk()')] Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1283358Reported-by:

commit 447d6275 upstream. Add some sanity check codes before actually accessing the endpoint via get_endpoint() in order to avoid the invalid access through a malformed USB descriptor. Mostly just checking bNumEndpoints, but in one place (snd_microii_spdif_default_get()), the validity of iface and altsetting index is checked as well.
