2022-12-19cifs: refresh root referralsPaulo Alcantara1-18/+22
Also refresh cached root referrals so the other cached referrals may have a better chance to have a working root server to issue the referrals on. Signed-off-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-12-19cifs: fix refresh of cached referralsPaulo Alcantara4-117/+37
We can't rely on cifs_tcon::ses to refresh cached referral as the server target might not respond to referrals, e.g. share is not hosted in a DFS root server. Consider the following mount //dom/dfs/link -> /root1/dfs/link -> /fs0/share where fs0 can't get a referral for "/root1/dfs/link". To simplify and fix the access of dfs root sessions, store the dfs root session pointer directly to new sessions so making it easier to select the appropriate ipc connection and use it for failover or cache refresh.

2022-12-19cifs: don't refresh cached referrals from unactive mountsPaulo Alcantara1-72/+1
There is no point refreshing cached referrals from unactive mounts as they will no longer be used and new mounts will either create or refresh them anyway. Signed-off-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>
2022-12-19cifs: share dfs connections and supersPaulo Alcantara9-369/+323
When matching DFS superblocks we can't rely on either the server's address or tcon's UNC name from mount(2) as the existing servers and tcons might be connected to somewhere else. Instead, check if superblock is dfs, and if so, match its original source pathname with the new mount's source pathname. For DFS connections, instead of checking server's address, match its referral path as it could be connected to different targets.

2022-12-19cifs: split out ses and tcon retrieval from mount_get_conns()Paulo Alcantara3-39/+78
Introduce and export two helpers for getting session and tcon during mount(2). Those will be used by dfs when retrieving sessions and tcons separately while chasing referrals. Besides, export cifs_mount_ctx structure as it will be used by dfs code as well. No functional changes.

2022-12-19cifs: set resolved ip in sockaddrPaulo Alcantara6-103/+55
All callers from dns_resolve_server_name_to_ip() used to convert the ip addr string back to sockaddr, so do that inside dns_resolve_server_name_to_ip() and avoid duplicating code. Signed-off-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>

2022-12-19cifs: get rid of mount options string parsingPaulo Alcantara7-247/+101
After switching to filesystem context support, we no longer need to handle mount options string when chasing dfs referrals. Now, we set the new values directly into smb3_fs_context. Start working on a separate source file to handle most dfs related mount functions as connect.c has already became too big. The remaining functions will be moved gradually in follow-up patches.

2022-12-19cifs: reduce roundtrips on create/qinfo requestsPaulo Alcantara5-84/+57
To work around some Window servers that return STATUS_OBJECT_NAME_INVALID on query infos under DFS namespaces that contain non-ASCII characters, we started checking for -ENOENT on every file open, and if so, then send additional requests to figure out whether it is a DFS link or not. It means that all those requests will be sent to every non-existing file. So, in order to reduce the number of roundtrips, check earlier whether status code is STATUS_OBJECT_NAME_INVALID and tcon supports dfs, and if so, then map -ENOENT to -EREMOTE so mount or automount will take care of chasing the DFS link -- if it isn't an DFS link, then -ENOENT will be returned appropriately.

2022-12-14fbdev: ssd1307fb: Drop duplicate NULL checks for PWM APIsAndy Shevchenko1-8/+4
pwm_disable() and pwm_put() are NULL-aware, no need to duplicate the check in the caller. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Helge Deller <deller@gmx.de>
2022-12-14fbdev: ssd1307fb: Drop optional dependencyAndy Shevchenko1-1/+0
Only a single out of three devices need a PWM, so from driver it's optional. Moreover it's a single driver in the entire kernel that currently selects PWM. Unfortunately this selection is a root cause of the circular dependencies when we want to enable optional PWM for some other drivers that select GPIOLIB.

2022-12-14KVM: x86: Add proper ReST tables for userspace MSR exits/flagsSean Christopherson1-8/+12
Add ReST formatting to the set of userspace MSR exits/flags so that the resulting HTML docs generate a table instead of malformed gunk. This also fixes a warning that was introduced by a recent cleanup of the relevant documentation (yay copy+paste). >> Documentation/virt/kvm/api.rst:7287: WARNING: Block quote ends without a blank line; unexpected unindent.

A remove callback just returning 0 is equivalent to no remove callback at all. So drop the useless function.

2022-12-14thermal/drivers/qcom/lmh: Fix irq handler return valueBjorn Andersson1-1/+1
After enough invocations the LMh irq is eventually reported as bad, because the handler doesn't return IRQ_HANDLED, fix this.

2022-12-14dt-bindings: thermal: rzg2l-thermal: Document RZ/Five SoCLad Prabhakar1-1/+1
The TSU block on the RZ/Five SoC is identical to one found on the RZ/G2UL SoC. "renesas,r9a07g043-tsu" compatible string will be used on the RZ/Five SoC so to make this clear, update the comment to include RZ/Five SoC. No driver changes are required as generic compatible string "renesas,rzg2l-tsu" will be used as a fallback on RZ/Five SoC.
