Howlett" <Liam.Howlett(a)oracle.com> Subject: maple_tree: add MAS_UNDERFLOW and MAS_OVERFLOW states Date: Thu, 21 Sep 2023 14:12:36 -0400 When updating the maple tree iterator to avoid rewalks, an issue was introduced when shifting beyond the limits. This can be seen by trying to go to the previous address of 0, which would set the maple node to MAS_NONE and keep the range as the last entry. Subsequent calls to mas_find() would then search upwards from mas->last and skip the value at mas->index/mas->last. This showed up as a bug in mprotect which skips the actual VMA at the current range after attempting to go to the previous VMA from 0. Since MAS_NONE is used for handling of the maple tree when it's a single entry at 0 (just a pointer), changing the handling of MAS_NONE in mas_find() would make the code more complicated and error prone. Furthermore, there was no way to tell which limit was hit, and thus which action to take (next or the entry at the current range). This solution is to add two states to track what happened with the previous iterator action. This allows for the expected behaviour of the next command to return the correct item (either the item at the range requested, or the next/previous). Tests are also added and updated accordingly.

Pedro Falcato contacted me on IRC with an mprotect regression which was bisected back to the iterator changes for maple tree. Root cause analysis showed the mas_prev() running off the end of the VMA space (previous from 0) followed by mas_find(), would skip the first value. This patchset introduces maple state underflow/overflow so the sequence of calls on the maple state will return what the user expects. This patch (of 2): Instead of constantly checking each possibility of the maple state, create a fast path that will skip over checking unlikely states.

[PATCH net v4 3/3] net: prevent address rewrite in kernel_bind()

by Jordan Rife

Similar to the change in commit 0bdf399342c5("net: Avoid address overwrite in kernel_connect"), BPF hooks run on bind may rewrite the address passed to kernel_bind(). This change 1) Makes a copy of the bind address in kernel_bind() to insulate callers. 2) Replaces direct calls to sock->ops->bind() with kernel_bind() Link: https://lore.kernel.org/netdev/20230912013332.2048422-1-jrife@google.com/ Fixes: 4fbac77d2d09 ("bpf: Hooks for sys_bind") Cc: stable(a)vger.kernel.org Signed-off-by: Jordan Rife <jrife(a)google.com> --- v3->v4: Remove precondition check for addrlen.

If the reference count hits 0 and its owner page gets unlocked, bh may be freed. However, bh->b_page is dereferenced to put the page after that, which may result in a use-after-free bug. This patch moves the release operation after unlocking and putting the page. NOTE: The function in question is only called in GC, and in combination with current userland tools, address translation using DAT does not occur in that function, so the code path that causes this issue will not be executed. However, it is possible to run that code path by intentionally modifying the userland GC library or by calling the GC ioctl directly.

[PATCH net v4 2/3] net: prevent rewrite of msg_name in sock_sendmsg()

by Jordan Rife

Callers of sock_sendmsg(), and similarly kernel_sendmsg(), in kernel space may observe their value of msg_name change in cases where BPF sendmsg hooks rewrite the send address. This has been confirmed to break NFS mounts running in UDP mode and has the potential to break other systems. This patch: 1) Creates a new function called __sock_sendmsg() with same logic as the old sock_sendmsg() function. 2) Replaces calls to sock_sendmsg() made by __sys_sendto() and __sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy, as these system calls are already protected. 3) Modifies sock_sendmsg() so that it makes a copy of msg_name if present before passing it down the stack to insulate callers from changes to the send address.

Linux 5.10.196

by Greg Kroah-Hartman

I'm announcing the release of the 5.10.196 kernel. This release is only needed by any 5.10.y user that uses configfs, it resolves a regression in 5.10.195 in that subsystem. Note that many kernel subsystems use configfs for configuration so to be safe, you probably want to upgrade if you are not sure. The updated 5.10.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.10.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 2 +- fs/configfs/dir.c | 2 -- 2 files changed, 1 insertion(+), 3 deletions(-) Greg Kroah-Hartman (2): Revert "configfs: fix a race in configfs_lookup()" Linux 5.10.196
