2023-07-25cifs: fix charset issue in reconnectionGravatar Winston Wen 1-0/+1
We need to specify charset, like "iocharset=utf-8", in mount options for Chinese path if the nls_default don't support it, such as iso8859-1, the default value for CONFIG_NLS_DEFAULT. But now in reconnection the nls_default is used, instead of the one we specified and used in mount, and this can lead to mount failure.

2023-07-14cifs: is_network_name_deleted should return a boolGravatar Shyam Prasad N 1-1/+1
Currently, is_network_name_deleted and it's implementations do not return anything if the network name did get deleted. So the function doesn't fully achieve what it advertizes. Changed the function to return a bool instead. It will now return true if the error returned is STATUS_NETWORK_NAME_DELETED and the share (tree id) was found to be connected. It returns false otherwise. Signed-off-by: Shyam Prasad N <sprasad@microsoft.com> Acked-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>

2023-06-28smb: client: fix shared DFS root mounts with different prefixesGravatar Paulo Alcantara 1-6/+4
When having two DFS root mounts that are connected to same namespace, same mount options but different prefix paths, we can't really use the shared @server->origin_fullpath when chasing DFS links in them. Move the origin_fullpath field to cifs_tcon structure so when having shared DFS root mounts with different prefix paths, and we need to chase any DFS links, dfs_get_automount_devname() will pick up the correct full path out of the @tcon that will be used for the new mount. Before patch mount.cifs //dom/dfs/dir /mnt/1 -o ... mount.cifs //dom/dfs /mnt/2 -o ... # shared server, ses, tcon # server: origin_fullpath=//dom/dfs/dir # @server->origin_fullpath + '/dir/link1' $ ls /mnt/2/dir/link1 ls: cannot open directory '/mnt/2/dir/link1': No such file or directory After patch mount.cifs //dom/dfs/dir /mnt/1 -o ... mount.cifs //dom/dfs /mnt/2 -o ... # shared server & ses # tcon_1: origin_fullpath=//dom/dfs/dir # tcon_2: origin_fullpath=//dom/dfs # @tcon_2->origin_fullpath + '/dir/link1' $ ls /mnt/2/dir/link1 dir0 dir1 dir10 dir3 dir5 dir6 dir7 dir9 target2_file.txt tsub Fixes: 8e3554150d6c ("cifs: fix sharing of DFS connections") Signed-off-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2023-06-11cifs: fix sockaddr comparison in iface_cmpGravatar Shyam Prasad N 1-37/+0
iface_cmp used to simply do a memcmp of the two provided struct sockaddrs. The comparison needs to do more based on the address family. Similar logic was already present in cifs_match_ipaddr. Doing something similar now.

2023-05-31Merge tag 'virt-to-pfn-for-arch-v6.5-2' of ↵Gravatar Arnd Bergmann 1-1/+1
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()
