[Devel] [PATCH vz8] vdso: fix VM_BUG_ON_PAGE(PageSlab(page)) on unmap

vdso_data is mapped to userspace which means that we can't use kmalloc() to allocate it. Kmalloc() doesn't even guarantee that we will get page aligned memory. kernel BUG at include/linux/mm.h:693! RIP: 0010:unmap_page_range+0x15f2/0x2630 Call Trace: unmap_vmas+0x11e/0x1d0

[Devel] [PATCH RH7 4/4] ms/net: drop bogus skb with CHECKSUM_PARTIAL and offset beyond end of trimmed packet

syzbot reproduces BUG_ON in skb_checksum_help(): tun creates (bogus) skb with huge partial-checksummed area and small ip packet inside. Then ip_rcv trims the skb based on size of internal ip packet, after that csum offset points beyond of trimmed skb. Then checksum_tg() called via netfilter hook

[Devel] [PATCH RH7 3/4] ms/net: make skb_partial_csum_set() more robust against overflows

From: Eric Dumazet syzbot managed to crash in skb_checksum_help() [1] : BUG_ON(offset + sizeof(__sum16) > skb_headlen(skb)); Root cause is the following check in skb_partial_csum_set() if (unlikely(start > skb_headlen(skb)) || unlikely((int)start + off >

[Devel] [PATCH RH7 2/4] ms/net: Fix usage of pskb_trim_rcsum

From: Ross Lagerwall In certain cases, pskb_trim_rcsum() may change skb pointers. Reinitialize header pointers afterwards to avoid potential use-after-frees. Add a note in the documentation of pskb_trim_rcsum(). Found by KASAN. Signed-off-by: Ross Lagerwall Signed-off-by: David S. Miller

[Devel] [PATCH RH7 1/4] ms/netfilter: xt_checksum: ignore gso skbs

From: Florian Westphal Satish Patel reports a skb_warn_bad_offload() splat caused by -j CHECKSUM rules: -A POSTROUTING -p tcp -m tcp --sport 80 -j CHECKSUM The CHECKSUM target has never worked with GSO skbs, and the above rule makes no sense as kernel will handle checksum updates on transmit.
