Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
cifs: Fix locking usage for tcon fields<br />
<br />
We used to use the cifs_tcp_ses_lock to protect a lot of objects<br />
that are not just the server, ses or tcon lists. We later introduced<br />
srv_lock, ses_lock and tc_lock to protect fields within the<br />
corresponding structs. This was done to provide a more granular<br />
protection and avoid unnecessary serialization.<br />
<br />
There were still a couple of uses of cifs_tcp_ses_lock to provide<br />
tcon fields. In this patch, I&#39;ve replaced them with tc_lock.
