2022-06-30vfs: fix copy_file_range() regression in cross-fs copiesAmir Goldstein
A regression has been reported by Nicolas Boichat, found while using the copy_file_range syscall to copy a tracefs file. Before commit 5dae222a5ff0 ("vfs: allow copy_file_range to copy across devices") the kernel would return -EXDEV to userspace when trying to copy a file across different filesystems. After this commit, the syscall doesn't fail anymore and instead returns zero (zero bytes copied), as this file's content is generated on-the-fly and thus reports a size of zero. Another regression has been reported by He Zhe - the assertion of WARN_ON_ONCE(ret == -EOPNOTSUPP) can be triggered from userspace when copying from a sysfs file whose read operation may return -EOPNOTSUPP. Since we do not have test coverage for copy_file_range() between any two types of filesystems, the best way to avoid these sort of issues in the future is for the kernel to be more picky about filesystems that are allowed to do copy_file_range(). This patch restores some cross-filesystem copy restrictions that existed prior to commit 5dae222a5ff0 ("vfs: allow copy_file_range to copy across devices"), namely, cross-sb copy is not allowed for filesystems that do not implement ->copy_file_range(). Filesystems that do implement ->copy_file_range() have full control of the result - if this method returns an error, the error is returned to the user. Before this change this was only true for fs that did not implement the ->remap_file_range() operation (i.e. nfsv3). Filesystems that do not implement ->copy_file_range() still fall-back to the generic_copy_file_range() implementation when the copy is within the same sb. This helps the kernel can maintain a more consistent story about which filesystems support copy_file_range(). nfsd and ksmbd servers are modified to fall-back to the generic_copy_file_range() implementation in case vfs_copy_file_range() fails with -EOPNOTSUPP or -EXDEV, which preserves behavior of server-side-copy. fall-back to generic_copy_file_range() is not implemented for the smb operation FSCTL_DUPLICATE_EXTENTS_TO_FILE, which is arguably a correct change of behavior.

The only difference between the ADL S and P GuC FWs is the HWConfig support. ADL-N does not support HWConfig, so we should use the same binary as ADL-S, otherwise the GuC might attempt to fetch a config table that does not exist. ADL-N is internally identified as an ADL-P, so we need to special-case it in the FW selection code.

2022-06-30NFS: restore module put when manager exits.NeilBrown
Commit f49169c97fce ("NFSD: Remove svc_serv_ops::svo_module") removed calls to module_put_and_kthread_exit() from threads that acted as SUNRPC servers and had a related svc_serv_ops structure. This was correct. It ALSO removed the module_put_and_kthread_exit() call from nfs4_run_state_manager() which is NOT a SUNRPC service. Consequently every time the NFSv4 state manager runs the module count increments and won't be decremented. So the nfsv4 module cannot be unloaded. So restore the module_put_and_kthread_exit() call.

Both PSFP stats and the port stats read by ocelot_check_stats_work() are indirectly read through the same mechanism - write to STAT_CFG:STAT_VIEW, read from SYS:STAT:CNT[n]. It's just that for port stats, we write STAT_VIEW with the index of the port, and for PSFP stats, we write STAT_VIEW with the filter index. So if we allow them to run concurrently, ocelot_check_stats_work() may change the view from vsc9959_psfp_counters_get(), and vice versa.

2022-06-30s390/archrandom: simplify back to earlier design and initialize earlierJason A. Donenfeld
s390x appears to present two RNG interfaces: - a "TRNG" that gathers entropy using some hardware function; and - a "DRBG" that takes in a seed and expands it. Previously, the TRNG was wired up to arch_get_random_{long,int}(), but it was observed that this was being called really frequently, resulting in high overhead. So it was changed to be wired up to arch_get_random_ seed_{long,int}(), which was a reasonable decision. Later on, the DRBG was then wired up to arch_get_random_{long,int}(), with a complicated buffer filling thread, to control overhead and rate. Fortunately, none of the performance issues matter much now. The RNG always attempts to use arch_get_random_seed_{long,int}() first, which means a complicated implementation of arch_get_random_{long,int}() isn't really valuable or useful to have around. And it's only used when reseeding, which means it won't hit the high throughput complications that were faced before. So this commit returns to an earlier design of just calling the TRNG in arch_get_random_seed_{long,int}(), and returning false in arch_get_ random_{long,int}(). Part of what makes the simplification possible is that the RNG now seeds itself using the TRNG at bootup. But this only works if the TRNG is detected early in boot, before random_init() is called. So this commit also causes that check to happen in setup_arch().
