2023-11-23smb: client: set correct file type from NFS reparse pointsPaulo Alcantara1-1/+7
Handle all file types in NFS reparse points as specified in MS-FSCC 2.1.2.6 Network File System (NFS) Reparse Data Buffer. The client is now able to set all file types based on the parsed NFS reparse point, which used to support only symlinks. This works for SMB1+. Before patch: $ mount.cifs //srv/share /mnt -o ... $ ls -l /mnt ls: cannot access 'block': Operation not supported ls: cannot access 'char': Operation not supported ls: cannot access 'fifo': Operation not supported ls: cannot access 'sock': Operation not supported total 1 l????????? ? ? ? ? ? block l????????? ? ? ? ? ? char -rwxr-xr-x 1 root root 5 Nov 18 23:22 f0 l????????? ? ? ? ? ? fifo l--------- 1 root root 0 Nov 18 23:23 link -> f0 l????????? ? ? ? ? ? sock After patch: $ mount.cifs //srv/share /mnt -o ... $ ls -l /mnt total 1 brwxr-xr-x 1 root root 123, 123 Nov 18 00:34 block crwxr-xr-x 1 root root 1234, 1234 Nov 18 00:33 char -rwxr-xr-x 1 root root 5 Nov 18 23:22 f0 prwxr-xr-x 1 root root 0 Nov 18 23:23 fifo lrwxr-xr-x 1 root root 0 Nov 18 23:23 link -> f0 srwxr-xr-x 1 root root 0 Nov 19 2023 sock Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>

2023-11-10cifs: handle when server stops supporting multichannelShyam Prasad N1-0/+1
When a server stops supporting multichannel, we will keep attempting reconnects to the secondary channels today. Avoid this by freeing extra channels when negotiate returns no multichannel support.

2023-11-09cifs: distribute channels across interfaces based on speedShyam Prasad N1-0/+2
Today, if the server interfaces RSS capable, we simply choose the fastest interface to setup a channel. This is not a scalable approach, and does not make a lot of attempt to distribute the connections. This change does a weighted distribution of channels across all the available server interfaces, where the weight is a function of the advertised interface speed. Also make sure that we don't mix rdma and non-rdma for channels. Signed-off-by: Shyam Prasad N <sprasad@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-11-09cifs: handle cases where a channel is closedShyam Prasad N1-0/+1
So far, SMB multichannel could only scale up, but not scale down the number of channels. In this series of patch, we now allow the client to deal with the case of multichannel disabled on the server when the share is mounted. With that change, we now need the ability to scale down the channels. This change allows the client to deal with cases of missing channels more gracefully.

2023-11-08cifs: Fix encryption of cleared, but unset rq_iter data buffersDavid Howells1-3/+9
Each smb_rqst struct contains two things: an array of kvecs (rq_iov) that contains the protocol data for an RPC op and an iterator (rq_iter) that contains the data payload of an RPC op. When an smb_rqst is allocated rq_iter is it always cleared, but we don't set it up unless we're going to use it. The functions that determines the size of the ciphertext buffer that will be needed to encrypt a request, cifs_get_num_sgs(), assumes that rq_iter is always initialised - and employs user_backed_iter() to check that the iterator isn't user-backed. This used to incidentally work, because ->user_backed was set to false because the iterator has never been initialised, but with commit f1b4cb650b9a0eeba206d8f069fcdc532bfbcd74[1] which changes user_backed_iter() to determine this based on the iterator type insted, a warning is now emitted: WARNING: CPU: 7 PID: 4584 at fs/smb/client/cifsglob.h:2165 smb2_get_aead_req+0x3fc/0x420 [cifs] ...

ITER_UBUF) which causes user_backed_iter() to return true. The code doesn't malfunction because it checks the size of the iterator - which is 0. Fix cifs_get_num_sgs() to ignore rq_iter if its count is 0, thereby bypassing the warnings. It might be better to explicitly initialise rq_iter to a zero-length ITER_BVEC, say, as it can always be reinitialised later.

With current implementation, when a nested DFS link is found during mount(2), the client follows the referral and then try to connect to all of its targets. If all targets failed, the client bails out rather than retrying remaining targets from previous referral. Fix this by stacking all referrals and targets so the client can retry remaining targets from previous referrals in case all targets of current referral have failed. Thanks to samba, this can be easily tested like below * Run the following under dfs folder in samba server $ ln -s "msdfs:srv\\bad-share" link1 $ ln -s "msdfs:srv\\dfs\\link1,srv\\good-share" link0 * Before patch $ mount.cifs //srv/dfs/link0 /mnt -o ... mount error(2): No such file or directory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)... * After patch $ mount.cifs //srv/dfs/link0 /mnt -o ... # ls /mnt bar fileshare1 sub Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into asm-generic This is an attempt to harden the typing on virt_to_pfn() and pfn_to_virt(). Making virt_to_pfn() a static inline taking a strongly typed (const void *) makes the contract of a passing a pointer of that type to the function explicit and exposes any misuse of the macro virt_to_pfn() acting polymorphic and accepting many types such as (void *), (unitptr_t) or (unsigned long) as arguments without warnings. For symmetry, we do the same with pfn_to_virt(). The problem with this inconsistent typing was pointed out by Russell King: https://lore.kernel.org/linux-arm-kernel/YoJDKJXc0MJ2QZTb@shell.armlinux.org.uk/ And confirmed by Andrew Morton: https://lore.kernel.org/linux-mm/20220701160004.2ffff4e5ab59a55499f4c736@linux-foundation.org/ So the recognition of the problem is widespread. These platforms have been chosen as initial conversion targets: - ARM - ARM64/Aarch64 - asm-generic (including for example x86) - m68k The idea is that if this goes in, it will block further misuse of the function signatures due to the large compile coverage, and then I can go in and fix the remaining architectures on a one-by-one basis. Some of the patches have been circulated before but were not picked up by subsystem maintainers, so now the arch tree is target for this series. It has passed zeroday builds after a lot of iterations in my personal tree, but there could be some randconfig outliers. New added or deeply hidden problems appear all the time so some minor fallout can be expected. * tag 'virt-to-pfn-for-arch-v6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: m68k/mm: Make pfn accessors static inlines arm64: memory: Make virt_to_pfn() a static inline ARM: mm: Make virt_to_pfn() a static inline asm-generic/page.h: Make pfn accessors static inlines xen/netback: Pass (void *) to virt_to_page() netfs: Pass a pointer to virt_to_page() cifs: Pass a pointer to virt_to_page() in cifsglob cifs: Pass a pointer to virt_to_page() riscv: mm: init: Pass a pointer to virt_to_page() ARC: init: Pass a pointer to virt_to_pfn() in init m68k: Pass a pointer to virt_to_pfn() virt_to_page() fs/proc/kcore.c: Pass a pointer to virt_addr_valid()
