2020-08-03mac80211: Do not report beacon loss if beacon filtering enabledLoic Poulain
mac80211.h says: Beacon filter support is advertised with the IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to enable beacon filter support whenever power save is enabled, that is IEEE80211_CONF_PS is set. When power save is enabled, the stack will not check for beacon loss and the driver needs to notify about loss of beacons with ieee80211_beacon_loss(). Some controllers may want to dynamically enable the beacon filter capabilities on power save entry (CONF_PS) and disable it on exit. This is the case for the wcn36xx driver which only supports beacon filtering in PS mode (no CONNECTION_MONITOR support). When the mac80211 beacon monitor timer expires, the beacon filter flag must be checked again in case it as been changed in between (e.g. vif moved to PS mode).

2020-08-03netfilter: flowtable: Set offload timeout when adding flowRoi Dayan
On heavily loaded systems the GC can take time to go over all existing conns and reset their timeout. At that time other calls like from nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as expired. To fix this when we set the offload bit we should also reset the timeout instead of counting on GC to finish first iteration over all conns before the initial timeout.

SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK (WFA) options. Those extensions use special status code values in the SAE commit messages (Authentication frame with transaction sequence number 1) to identify which extension is in use. mac80211 was interpreting those new values as the AP denying authentication and that resulted in failure to complete SAE authentication in some cases.

2020-08-02mm: rewrite wait_on_page_bit_common() logicLinus Torvalds
It turns out that wait_on_page_bit_common() had several problems, ranging from just unfair behavioe due to re-queueing at the end of the wait queue when re-trying, and an outright bug that could result in missed wakeups (but probably never happened in practice). This rewrites the whole logic to avoid both issues, by simply moving the logic to check (and possibly take) the bit lock into the wakeup path instead. That makes everything much more straightforward, and means that we never need to re-queue the wait entry: if we get woken up, we'll be notified through WQ_FLAG_WOKEN, and the wait queue entry will have been removed, and everything will have been done for us.

2020-08-02cifs: document and cleanup dfs mountPaulo Alcantara
cifs_mount() for DFS mounts is for a long time way too complex to follow, mostly because it lacks some documentation, does a lot of operations like resolving DFS roots and links, checking for path components, perform failover, crap code, etc. Besides adding some documentation to it, do some cleanup and ensure that the following is implemented and supported: * non-DFS mounts * DFS failover * DFS root mounts - tcon and cifs_sb must contain DFS path (NOT including prefix) - if prefix path, then save it in cifs_sb and it must not be changed * DFS link mounts - tcon and cifs_sb must contain DFS path (including prefix) - if prefix path, then save it in cifs_sb and it may be changed * prevent recursion on broken link referrals (MAX_NESTED_LINKS) * check every path component of the currently resolved target (including prefix), and chase them accordingly * make sure that DFS referrals go through newly resolved root servers Signed-off-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Reviewed-by: Aurelien Aptel <aaptel@suse.com> Signed-off-by: Steve French <stfrench@microsoft.com>

For DFS root mounts that contain a prefix path, do not change them after failover. E.g., if the user mounts //srvA/root/dir1 and then lost connection to srvA, it will reconnect to //srvB/root/dir1 In case of DFS links, which may resolve to different prefix paths depending on their list of targets, the following must be supported: - mount //srvA/root/link/bar - connect to //srvA/share - set prefix path to "bar" - lost connection to srvA - reconnect to next target: //srvB/share/foo - set new prefix path to "foo/bar" In cifs_tree_connect(), check the server_type field of the cached DFS referral to determine whether or not prefix path should be updated.

Currently if the call dfs_cache_get_tgt_share fails we cannot fully guarantee that share and prefix are set to NULL and the next iteration of the loop can end up potentially double freeing these pointers. Since the semantics of dfs_cache_get_tgt_share are ambiguous for failure cases with the setting of share and prefix (currently now and the possibly the future), it seems prudent to set the pointers to NULL when the objects are free'd to avoid any double frees.

Handling a lease break for the cached root didn't free the smb2_lease_break_work allocation, resulting in a leak: unreferenced object 0xffff98383a5af480 (size 128): comm "cifsd", pid 684, jiffies 4294936606 (age 534.868s) hex dump (first 32 bytes): c0 ff ff ff 1f 00 00 00 88 f4 5a 3a 38 98 ff ff ..........Z:8... 88 f4 5a 3a 38 98 ff ff 80 88 d6 8a ff ff ff ff ..Z:8........... backtrace: [<0000000068957336>] smb2_is_valid_oplock_break+0x1fa/0x8c0 [<0000000073b70b9e>] cifs_demultiplex_thread+0x73d/0xcc0 [<00000000905fa372>] kthread+0x11c/0x150 [<0000000079378e4e>] ret_from_fork+0x22/0x30 Avoid this leak by only allocating when necessary.

2020-08-02netfilter: nf_tables: report EEXIST on overlapsPablo Neira Ayuso
Replace EBUSY by EEXIST in the following cases: - If the user adds a chain with a different configuration such as different type, hook and priority. - If the user adds a non-base chain that clashes with an existing basechain. - If the user adds a { key : value } mapping element and the key exists but the value differs. - If the device already belongs to an existing flowtable. User describe that this error reporting is confusing: - https://bugzilla.netfilter.org/show_bug.cgi?id=1176 - https://bugzilla.netfilter.org/show_bug.cgi?id=1413 Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
