Subject: PCI/MSI: Fix memory leak in free_msi_irqs()
|
||||
Origin: https://git.kernel.org/linus/b701c0b1fe819a2083fc6ec5332e0e4492b9516d
|
||||
|
||||
free_msi_irqs() is leaking memory, since list_for_each_entry(entry,
|
||||
&dev->msi_list, list) {...} is never executed, because dev->msi_list is
|
||||
made empty by the loop just above this one.
|
||||
|
||||
Fix it by relying on zero termination of attribute array like
|
||||
populate_msi_sysfs() does.

||||

||||

Subject: fs,userns: Change inode_capable to capable_wrt_inode_uidgid
|
||||
Origin: https://git.kernel.org/linus/23adbe12ef7d3d4195e80800ab36b37bee28cd03
|
||||
|
||||
The kernel has no concept of capabilities with respect to inodes; inodes
|
||||
exist independently of namespaces. For example, inode_capable(inode,
|
||||
CAP_LINUX_IMMUTABLE) would be nonsense.
|
||||
|
||||
This patch changes inode_capable to check for uid and gid mappings and
|
||||
renames it to capable_wrt_inode_uidgid, which should make it more
|
||||
obvious what it does.
|
||||
|
||||
Fixes CVE-2014-4014.

else we may fail to forward skb even if original fragments do fit
|
||||
outgoing link mtu:
|
||||
|
||||
1. remote sends 2k packets in two 1000 byte frags, DF set
|
||||
2. we want to forward but only see '2k > mtu and DF set'
|
||||
3. we then send icmp error saying that outgoing link is 1500
|
||||
|
||||
But original sender never sent a packet that would not fit
|
||||
the outgoing link.
|
||||
|
||||
Setting local_df makes outgoing path test size vs.
|
||||
IPCB(skb)->frag_max_size, so we will still send the correct
|
||||
error in case the largest original size did not fit
|
||||
outgoing link mtu.
