If we negotiate SMB 2.1 and higher version of the protocol and a server supports large read buffer size, we need to consume 1 credit per 65536 bytes. So, we need to know how many credits we have and obtain the required number of them before constructing a readdata structure in readpages and user read. Reviewed-by:

If a server changes maximum buffer size for read requests (rsize) on reconnect we can fail on repeating with a big size buffer on -EAGAIN error in cifs_read. Fix this by checking rsize all the time before repeating requests. Reviewed-by:

If we get into read_into_pages() from cifs_readv_receive() and then loose a network, we issue cifs_reconnect that moves all mids to a private list and issue their callbacks. The callback of the async read request sets a mid to retry, frees it and wakes up a process that waits on the rdata completion. After the connection is established we return from read_into_pages() with a short read, use the mid that was freed before and try to read the remaining data from the a newly created socket. Both actions are not what we want to do. In reconnect cases (-EAGAIN) we should not mask off the error with a short read but should return the error code instead. Acked-by:

Th AF_ALG socket was missing a security label (e.g. SELinux) which means that socket was in "unlabeled" state. This was recently demonstrated in the cryptsetup package (cryptsetup v1.6.5 and later.) See https://bugzilla.redhat.com/show_bug.cgi?id=1115120 This patch clones the sock's label from the parent sock and resolves the issue (similar to AF_BLUETOOTH protocol family).

PG_head_mask was added into VMCOREINFO to filter huge pages in b3acc56b ("kexec: save PG_head_mask in VMCOREINFO"), but makedumpfile still need another symbol to filter *hugetlbfs* pages. If a user hope to filter user pages, makedumpfile tries to exclude them by checking the condition whether the page is anonymous, but hugetlbfs pages aren't anonymous while they also be user pages. We know it's possible to detect them in the same way as PageHuge(), so we need the start address of free_huge_page(): int PageHuge(struct page *page) { if (!PageCompound(page)) return 0; page = compound_head(page); return get_compound_page_dtor(page) == free_huge_page; } For that reason, this patch changes free_huge_page() into public to export it to VMCOREINFO.

do_fault_around() expects fault_around_bytes rounded down to nearest page order. Instead of calling rounddown_pow_of_two every time in fault_around_pages()/fault_around_mask() we could do round down when user changes fault_around_bytes via debugfs interface. This also fixes bug when user set fault_around_bytes to 0. Result of rounddown_pow_of_two(0) is not defined, therefore fault_around_bytes == 0 doesn't work without this patch. Let's set fault_around_bytes to PAGE_SIZE if user sets to something less than PAGE_SIZE [akpm@linux-foundation.org: tweak code layout] Fixes: a9b0f861("mm: nominate faultaround area in bytes rather than page order") Signed-off-by:
