[ Upstream commit c8e92757 ] Currently, project quota could be changed by fssetxattr ioctl, and existed permission check inode_owner_or_capable() is obviously not enough, just think that common users could change project id of file, that could make users to break project quota easily. This patch try to follow same regular of xfs project quota: "Project Quota ID state is only allowed to change from within the init namespace. Enforce that restriction only if we are trying to change the quota ID state. Everything else is allowed in user namespaces." Besides that, check and set project id'state should be an atomic operation, protect whole operation with inode lock. Signed-off-by:

[ Upstream commit 4a63c1ff ] For userspace to tell the difference between an random signal and an exception, the exception must include siginfo information. Using SEND_SIG_FORCED for SIGSEGV is thus wrong, and it will result in userspace seeing si_code == SI_USER (like a random signal) instead of si_code == SI_KERNEL or a more specific si_code as all exceptions deliver. Therefore replace force_sig_info(SIGSEGV, SEND_SIG_FORCE, current) with force_sig(SIG_SEGV, current) which gets this right and is shorter and easier to type.

[ Upstream commit 86989c41 ] If the first process started (aka /sbin/init) receives a SIGKILL it will panic the system if it is delivered. Making the system unusable and undebugable. It isn't much better if the first process started receives SIGSTOP. So always ignore SIGSTOP and SIGKILL sent to init. This is done in a separate clause in sig_task_ignored as force_sig_info can clear SIG_UNKILLABLE and this protection should work even then. Reviewed-by:

[ Upstream commit 2bf4b33f ] If the set_txreq_header_agh() function returns an error, the exit path is chosen. In this path, the code fails to set the return value. This will cause the caller to not realize an error has occurred. Set the return value correctly in the error path. Signed-off-by:

[ Upstream commit 6df0580b ] Various documented examples on how to set up tx99 with ath9k rely on setting up a regular monitor interface for setting the channel. My previous patch "ath9k: fix tx99 with monitor mode interface" made it possible to set it up this way again. However, it was removing support for using an active monitor interface, which is required for controlling the bitrate as well, since the bitrate is not passed down with a regular monitor interface. This patch partially reverts the previous one, but keeps support for using a regular monitor interface to keep documented steps working in cases where the bitrate does not matter Fixes: d9c52fd1 ("ath9k: fix tx99 with monitor mode interface") Signed-off-by:

[ Upstream commit dcc960b2 ] Users of the mce_register_decode_chain() are called for every logged error. EDAC drivers should check: 1) Is this a memory error? [bit 7 in status register] 2) Is there a valid address? [bit 58 in status register] 3) Is the address a system address? [bitfield 8:6 in misc register] The sb_edac driver performed test "1" twice. Waited far too long to perform check "2". Didn't do check "3" at all. Fix it by moving the test for valid address from sbridge_mce_output_error() into sbridge_mce_check_error() and add a test for the type immediately after. Delete the redundant check for the type of the error from sbridge_mce_output_error(). Signed-off-by:

[ Upstream commit 83ef4fb7 ] Func jz4780_dma_desc_residue() expects the index to the next hw descriptor as its last parameter. Caller func jz4780_dma_tx_status(), however, applied modulus before passing it. When the current hw descriptor was last in the list, the index passed became zero. The resulting excess of reported residue especially caused problems with cyclic DMA transfer clients, i.e. ALSA AIC audio output, which rely on this for determining current DMA location within buffer. Combined with the recent and related residue-reporting fixes, spurious ALSA audio underruns on jz4770 hardware are now fixed. Signed-off-by:

[ Upstream commit 0eae4958 ] The vbus rise & fall interrupts are used to enable and disable U3 function of device automatically, this cause some issues when class driver is initialized as deactivated, and will skip over software-controlled connect by pullup(), but UDC wants to keep disconnect until usb_gadget_activate() is called which calls pullup() if needed. So we disable vbus rise & fall interrupts and just use pullup() to enable & disable U3 function, and reset mtu3 state when disconnect instead when vbus fall. Signed-off-by:

This also introduced a compiler warning for a potentially uninitialised variable in the case no CODECs are present. This should never be the case as the DAI link must by definition contain at least 1 CODEC however probably best to avoid the compiler warning by initialising ret to zero. Signed-off-by:
