[ Upstream commit f1157695 ] Currently the wmi command for setting probe request oui, needed for mac randomization, is sent during the mac register. At this time, during the driver init the wmi has already been detached. This can cause unexpected behavior since the firmware is already down and the wmi has been detached. Send the wmi command for setting probe request oui during the driver start. This will make sure that the firmware is started and wmi is initialized before we send this command.

[ Upstream commit 2258ee58 ] Beacons are not updated to reflect TIM changes. This is not compliant with power-saving client stations as the beacons do not have valid TIM and can cause the network to stall at random occasions and to have highly variable latencies. Fix it by updating beacon templates on mac80211 set_tim callback. Addresses an issue described in: https://marc.info/?i=20180911163534.21312d08%20()%20manjaroSigned-off-by:

[ Upstream commit 473af09b ] eeh_add_to_parent_pe() sometimes removes the EEH_PE_KEEP flag, but it incorrectly removes it from pe->type, instead of pe->state. However, rather than clearing it from the correct field, remove it. Inspection of the code shows that it can't ever have had any effect (even if it had been cleared from the correct field), because the field is never tested after it is cleared by the statement in question. The clear statement was added by commit 807a827d ("powerpc/eeh: Keep PE during hotplug"), but it didn't explain why it was necessary. Signed-off-by:

[ Upstream commit 1a855eac ] As of commit 10c77dba ("powerpc/boot: Fix build failure in 32-bit boot wrapper") the opal code is hidden behind CONFIG_PPC64_BOOT_WRAPPER, but the boot wrapper avoids include/linux, so it does not get the normal Kconfig flags.

[ Upstream commit d2130e82 ] The way we calculate logbuf free space percentage overflows signed integer: int free; free = __LOG_BUF_LEN - log_next_idx; pr_info("early log buf free: %u(%u%%)\n", free, (free * 100) / __LOG_BUF_LEN); We support LOG_BUF_LEN of up to 1<<25 bytes. Since setup_log_buf() is called during early init, logbuf is mostly empty, so __LOG_BUF_LEN - log_next_idx is close to 1<<25. Thus when we multiply it by 100, we overflow signed integer value range: 100 is 2^6 + 2^5 + 2^2. Example, booting with LOG_BUF_LEN 1<<25 and log_buf_len=2G boot param: [ 0.075317] log_buf_len: -2147483648 bytes [ 0.075319] early log buf free: 33549896(-28%) Make "free" unsigned integer and use appropriate printk() specifier.

[ Upstream commit 3ac37a93 ] Prior to commit 5c2992ee ("printk: remove console flushing special cases for partial buffered lines") we would do console_cont_flush() for each pr_cont() to print cont fragments, so console_unlock() would actually print data: pr_cont(); console_lock(); console_unlock() console_cont_flush(); // print cont fragment ... pr_cont(); console_lock(); console_unlock() console_cont_flush(); // print cont fragment We don't do console_cont_flush() anymore, so when we do pr_cont() console_unlock() does nothing (unless we flushed the cont buffer): pr_cont(); console_lock(); console_unlock(); // noop ... pr_cont(); console_lock(); console_unlock(); // noop ... pr_cont(); cont_flush(); console_lock(); console_unlock(); // print data We also wakeup klogd purposelessly for pr_cont() output - un-flushed cont buffer is not stored in log_buf; there is nothing to pull. Thus we can console_lock()/console_unlock()/wake_up_klogd() only when we know that we log_store()-ed a message and there is something to print to the consoles/syslog.

[ Upstream commit 22a8118d ] After allocation, output and decomp_output both point to memory chunks of size COMP_BUF_SIZE. Then, only the first bytes are zeroed out using sizeof(COMP_BUF_SIZE) as parameter to memset(), because sizeof(COMP_BUF_SIZE) provides the size of the constant and not the size of allocated memory. Instead, the whole allocated memory is meant to be zeroed out. Use COMP_BUF_SIZE as parameter to memset() directly in order to accomplish this.

commit 2d691aec upstream. set_page_dirty says: For pages with a mapping this should be done under the page lock for the benefit of asynchronous memory errors who prefer a consistent dirty state. This rule can be broken in some special cases, but should be better not to. Under those rules, it is only safe for us to use the plain set_page_dirty calls for shmemfs/anonymous memory. Userptr may be used with real mappings and so needs to use the locked version (set_page_dirty_lock). However, following a try_to_unmap() we may want to remove the userptr and so call put_pages(). However, try_to_unmap() acquires the page lock and so we must avoid recursively locking the pages ourselves -- which means that we cannot safely acquire the lock around set_page_dirty(). Since we can't be sure of the lock, we have to risk skip dirtying the page, or else risk calling set_page_dirty() without a lock and so risk fs corruption.

commit d791cfcb upstream. When we hot unplug a virtserialport and then try to hot plug again, it fails: (qemu) chardev-add socket,id=serial0,path=/tmp/serial0,server,nowait (qemu) device_add virtserialport,bus=virtio-serial0.0,nr=2,\ chardev=serial0,id=serial0,name=serial0 (qemu) device_del serial0 (qemu) device_add virtserialport,bus=virtio-serial0.0,nr=2,\ chardev=serial0,id=serial0,name=serial0 kernel error: virtio-ports vport2p2: Error allocating inbufs qemu error: virtio-serial-bus: Guest failure in adding port 2 for device \ virtio-serial0.0 This happens because buffers for the in_vq are allocated when the port is added but are not released when the port is unplugged. They are only released when virtconsole is removed (see a7a69ec0) To avoid the problem and to be symmetric, we could allocate all the buffers in init_vqs() as they are released in remove_vqs(), but it sounds like a waste of memory. Rather than that, this patch changes add_port() logic to ignore ENOSPC error in fill_queue(), which means queue has already been filled.

commit b0391479 upstream. When converting milliseconds to microseconds in commit fffa6af9 ("gpio: max77620: Use correct unit for debounce times") some ~1 ms gaps were introduced between the various ranges supported by the controller. Fix this by changing the start of each range to the value immediately following the end of the previous range. This way a debounce time of, say 8250 us will translate into 16 ms instead of returning an -EINVAL error. Typically the debounce delay is only ever set through device tree and specified in milliseconds, so we can never really hit this issue because debounce times are always a multiple of 1000 us. The only notable exception for this is drivers/mmc/host/mmc-spi.c where the CD GPIO is requested, which passes a 1 us debounce time. According to a comment preceeding that code this should actually be 1 ms (i.e. 1000 us). Reported-by:

This is not sufficient to avoid hitting a WARN() in the traffic path: for example, it is possible to replace a valid entry with a new one having 0 extended keys, thus causing splats in dmesg like: pedit BUG: index 42 WARNING: CPU: 2 PID: 4054 at net/sched/act_pedit.c:410 tcf_pedit_act+0xc84/0x1200 [act_pedit] [...] RIP: 0010:tcf_pedit_act+0xc84/0x1200 [act_pedit] Code: 89 fa 48 c1 ea 03 0f b6 04 02 84 c0 74 08 3c 03 0f 8e ac 00 00 00 48 8b 44 24 10 48 c7 c7 a0 c4 e4 c0 8b 70 18 e8 1c 30 95 ea <0f> 0b e9 a0 fa ff ff e8 00 03 f5 ea e9 14 f4 ff ff 48 89 58 40 e9 RSP: 0018:ffff888077c9f320 EFLAGS: 00010286 RAX: 0000000000000000 RBX: 0000000000000000 RCX: ffffffffac2983a2 RDX: 0000000000000001 RSI: 0000000000000008 RDI: ffff888053927bec RBP: dffffc0000000000 R08: ffffed100a726209 R09: ffffed100a726209 R10: 0000000000000001 R11: ffffed100a726208 R12: ffff88804beea780 R13: ffff888079a77400 R14: ffff88804beea780 R15: ffff888027ab2000 FS: 00007fdeec9bd740(0000) GS:ffff888053900000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007ffdb3dfd000 CR3: 000000004adb4006 CR4: 00000000001606e0 Call Trace: tcf_action_exec+0x105/0x3f0 tcf_classify+0xf2/0x410 __dev_queue_xmit+0xcbf/0x2ae0 ip_finish_output2+0x711/0x1fb0 ip_output+0x1bf/0x4b0 ip_send_skb+0x37/0xa0 raw_sendmsg+0x180c/0x2430 sock_sendmsg+0xdb/0x110 __sys_sendto+0x257/0x2b0 __x64_sys_sendto+0xdd/0x1b0 do_syscall_64+0xa5/0x4e0 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7fdeeb72e993 Code: 48 8b 0d e0 74 2c 00 f7 d8 64 89 01 48 83 c8 ff c3 66 0f 1f 44 00 00 83 3d 0d d6 2c 00 00 75 13 49 89 ca b8 2c 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 34 c3 48 83 ec 08 e8 4b cc 00 00 48 89 04 24 RSP: 002b:00007ffdb3de8a18 EFLAGS: 00000246 ORIG_RAX: 000000000000002c RAX: ffffffffffffffda RBX: 000055c81972b700 RCX: 00007fdeeb72e993 RDX: 0000000000000040 RSI: 000055c81972b700 RDI: 0000000000000003 RBP: 00007ffdb3dea130 R08: 000055c819728510 R09: 0000000000000010 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000040 R13: 000055c81972b6c0 R14: 000055c81972969c R15: 0000000000000080 Fix this moving the check on 'nkeys' earlier in tcf_pedit_init(), so that attempts to install rules having 0 keys are always rejected with -EINVAL.

[ Upstream commit d658c8f56ec7b3de8051a24afb25da9ba3c388c5 ] The "ivm->vf" variable is a u32, but the problem is that a number of drivers cast it to an int and then forget to check for negatives. An example of this is in the cxgb4 driver. drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c 2890 static int cxgb4_mgmt_get_vf_config(struct net_device *dev, 2891 int vf, struct ifla_vf_info *ivi)

[ Upstream commit 1fc16577 ] The helper mlxsw_sp_ipip_dev_ul_tb_id() determines the underlay VRF of a GRE tunnel. For a tunnel without a bound device, it uses the same VRF that the tunnel is in. However in Linux, a GRE tunnel without a bound device uses the main VRF as the underlay. Fix the function accordingly. mlxsw further assumed that moving a tunnel to a different VRF could cause conflict in local tunnel endpoint address, which cannot be offloaded. However, the only way that an underlay could be changed by moving the tunnel device itself is if the tunnel device does not have a bound device. But in that case the underlay is always the main VRF, so there is no opportunity to introduce a conflict by moving such device. Thus this check constitutes a dead code, and can be removed, which do.
