Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/smc: Do not re-initialize smc hashtables<br /> <br /> INIT_HLIST_HEAD(&amp;smc_v*_hashinfo.ht) are called after smc_nl_init(),<br /> proto_register() and sock_register(). This can lead to smc_v*_hashinfo.ht<br /> being reset even though hash entries already exist and are being used,<br /> possibly resulting in a corrupted list.<br /> <br /> Remove unnecessary and dangerous re-initialisation of smc_v*_hashinfo.ht in<br /> smc_init(); it is implicitly initialised to zero anyhow. Add<br /> HLIST_HEAD_INIT to the definitions for clarity.
