mainline inclusion from linux-next/master commit ded52fbe category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- After setxattr, the nfsv3 cached the acl which set by user. But at the backend, the shared file system (eg. ext4) will check the acl, if it can merged with mode, it won't add acl to the file. So, the nfsv3 cached acl is redundant. Don't 'set_cached_acl' when setxattr. Signed-off-by:

But the generic_fillattr has not fill that, so add ext2_getattr to do this. This can fix generic/424 while testing ext2. Reviewed-by:

commit 63530aba upstream. syzbot found that ax25 routes where not properly protected against concurrent use [1]. In this particular report the bug happened while copying ax25->digipeat. Fix this problem by making sure we call ax25_get_route() while ax25_route_lock is held, so that no modification could happen while using the route. The current two ax25_get_route() callers do not sleep, so this change should be fine. Once we do that, ax25_get_route() no longer needs to grab a reference on the found route.

commit bdcc5bc2 upstream. Since mISDN_close() uses dev->pending to iterate over active timers, there is a chance that one timer got removed from the ->pending list in dev_expire_timer() but that the thread has not called yet wake_up_interruptible() So mISDN_close() could miss this and free dev before completion of at least one dev_expire_timer() syzbot was able to catch this race : BUG: KASAN: use-after-free in

commit cf657d22 upstream. Due to quadratic behavior of x25_new_lci(), syzbot was able to trigger an rcu stall. Fix this by not blocking BH for the whole duration of the function, and inserting a reschedule point when possible. If we care enough, using a bitmap could get rid of the quadratic behavior. syzbot report : rcu: INFO: rcu_preempt self-detected stall on CPU rcu: 0-...!: (10500 ticks this GP)

commit e7afe6c1 upstream. While trying to reproduce a reported kernel panic on arm64, I discovered that AUTH_GSS basically doesn't work at all with older enctypes on arm64 systems with CONFIG_VMAP_STACK enabled. It turns out there still a few places using stack memory with scatterlists, causing krb5_encrypt() and krb5_decrypt() to produce incorrect results (or a BUG if CONFIG_DEBUG_SG is enabled). Tested with cthon on v4.0/v4.1/v4.2 with krb5/krb5i/krb5p using des3-cbc-sha1 and arcfour-hmac-md5. Signed-off-by:

[ Upstream commit c09551c6 ] According to the algorithm described in the comment block at the beginning of ip_rt_send_redirect, the host should try to send 'ip_rt_redirect_number' ICMP redirect packets with an exponential backoff and then stop sending them at all assuming that the destination ignores redirects. If the device has previously sent some ICMP error packets that are rate-limited (e.g TTL expired) and continues to receive traffic, the redirect packets will never be transmitted. This happens since peer->rate_tokens will be typically greater than 'ip_rt_redirect_number' and so it will never be reset even if the redirect silence timeout (ip_rt_redirect_silence) has elapsed without receiving any packet requiring redirects. Fix it by using a dedicated counter for the number of ICMP redirect packets that has been sent by the host I have not been able to identify a given commit that introduced the issue since ip_rt_send_redirect implements the same rate-limiting algorithm from commit 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

[ Upstream commit 3b89ea9c ] The features attribute is of type u64 and stored in the native endianes on the system. The for_each_set_bit() macro takes a pointer to a 32 bit array and goes over the bits in this area. On little Endian systems this also works with an u64 as the most significant bit is on the highest address, but on big endian the words are swapped. When we expect bit 15 here we get bit 47 (15 + 32). This patch converts it more or less to its own for_each_set_bit() implementation which works on 64 bit integers directly. This is then completely in host endianness and should work like expected. Fixes: fd867d51 ("net/core: generic support for disabling netdev features down stack") Signed-off-by:

[ Upstream commit 28946040 ] The function-local variable "delay" enters the loop interpreted as delay in bits. However, inside the loop it gets overwritten by the result of mlxsw_sp_pg_buf_delay_get(), and thus leaves the loop as quantity in cells. Thus on second and further loop iterations, the headroom for a given priority is configured with a wrong size. Fix by introducing a loop-local variable, delay_cells. Rename thres to thres_cells for consistency. Fixes: f417f04d ("mlxsw: spectrum: Refactor port buffer configuration") Signed-off-by:

[ Upstream commit 7c0db24c ] The GPIO interrupt controller on the espressobin board only supports edge interrupts. If one enables the use of hardware interrupts in the device tree for the 88E6341, it is possible to miss an edge. When this happens, the INTn pin on the Marvell switch is stuck low and no further interrupts occur. I found after adding debug statements to mv88e6xxx_g1_irq_thread_work() that there is a race in handling device interrupts (e.g. PHY link interrupts). Some interrupts are directly cleared by reading the Global 1 status register. However, the device interrupt flag, for example, is not cleared until all the unmasked SERDES and PHY ports are serviced. This is done by reading the relevant SERDES and PHY status register. The code only services interrupts whose status bit is set at the time of reading its status register. If an interrupt event occurs after its status is read and before all interrupts are serviced, then this event will not be serviced and the INTn output pin will remain low. This is not a problem with polling or level interrupts since the handler will be called again to process the event. However, it's a big problem when using level interrupts. The fix presented here is to add a loop around the code servicing switch interrupts. If any pending interrupts remain after the current set has been handled, we loop and process the new set. If there are no pending interrupts after servicing, we are sure that INTn has gone high and we will get an edge when a new event occurs. Tested on espressobin board.

Currently if number of CQ irq vectors (fixed 16) are less than nr_cpus, it will fail to allocate msi interrupt. So allocate number of CQ irq vectors from 1 to 16. And also if offline those cpus assocationed with CQ irq vectors, no need to issue internal abort command to the queue, or internal abort command will be timeout as there is no cpu processing the CQ interrupt.

scsi: hisi_sas: Reject request of setting minimum_linkrate exceed 1.5 Gbit at directly attached environment At directly attached env, we found out that user can successfully set a higher linkrate to minimum_linkrate than negotiated_linkrate. Like below: maximum_linkrate: 6.0 Gbit minimum_linkrate: 6.0 Gbit negotiated_linkrate: 3.0 Gbit It mean that the bound of max and min linkrate cannot limit the negotiated linkrate. This may cause trouble to user. Actually, we only send maximum_linkrate to SAS controller, and SAS controller will try all the linkrate under the setting value and finally negotiate with the highest possible linkrate. So to the SAS controller at directly attached env, the min linkrate is unnecessary. If we want to avoid this issue, the best way is to reject the request of setting minimum_linkrate exceed 1.5 Gbit.
