Josef Bacik 80745460b4 proc: use kvzalloc for our kernel buffer ... Since sysctl: pass kernel pointers to ->proc_handler we have been pre-allocating a buffer to copy the data from the proc handlers into, and then copying that to userspace. The problem is this just blindly kzalloc()'s the buffer size passed in from the read, which in the case of our 'cat' binary was 64kib. Order-4 allocations are not awesome, and since we can potentially allocate up to our maximum order, so use kvzalloc for these buffers. [willy@infradead.org: changelog tweaks] Link: https://lkml.kernel.org/r/6345270a2c1160b89dd5e6715461f388176899d1.1612972413.git.josef@toxicpanda.com Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") Change-Id: I03ad7285b4c57d2c53aff84e369ef5edbeef7679 Signed-off-by: Josef Bacik <josef@toxicpanda.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Acked-by: Vlastimil Babka <vbabka@suse.cz> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Alexey Dobriyan <adobriyan@gmail.com> CC: Matthew Wilcox <willy@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Tashfin Shakeer Rhythm <tashfinshakeerrhythm@gmail.com>		2026-02-01 20:39:16 -08:00
