      Blackfin: outs[lwb]: make sure count is greater than 0 · bb7b1129
      Mike Frysinger authored
      
      
      Some devices will use the outs* funcs with a length of zero, so make sure
      we do not write any data in that case.

      DNS: Fix a NULL pointer deref when trying to read an error key [CVE-2011-1076] · 1362fa07
      David Howells authored
      When a DNS resolver key is instantiated with an error indication, attempts to
      read that key will result in an oops because user_read() is expecting there to
      be a payload - and there isn't one [CVE-2011-1076].
      
      Give the DNS resolver key its own read handler that returns the error cached in
      key->type_data.x[0] as an error rather than crashing.
      
      Also make the kenter() at the beginning of dns_resolver_instantiate() limit the
      amount of data it prints, since the data is not necessarily NUL-terminated.
      
      The buggy code was added in:
      
      	commit 4a2d7892
      
      
      	Author: Wang Lei <wang840925@gmail.com>
      	Date:   Wed Aug 11 09:37:58 2010 +0100
      	Subject: DNS: If the DNS server returns an error, allow that to be cached [ver #2]
      
      This can trivially be reproduced by any user with the following program
      compiled with -lkeyutils:
      
      	#include <stdlib.h>
      	#include <keyutils.h>
      	#include <err.h>
      	static char payload[] = "#dnserror=6";
      	int main()
      	{
      		key_serial_t key;
      		key = add_key("dns_resolver", "a", payload, sizeof(payload),
      			      KEY_SPEC_SESSION_KEYRING);
      		if (key == -1)
      			err(1, "add_key");
      		if (keyctl_read(key, NULL, 0) == -1)
      			err(1, "read_key");
      		return 0;
      	}
      
      What should happen is that keyctl_read() reports error 6 (ENXIO) to the user:
      
      	dns-break: read_key: No such device or address
      
      but instead the kernel oopses.
      
      This cannot be reproduced with the 'keyutils add' or 'keyutils padd' commands
      as both of those cut the data down below the NUL termination that must be
      included in the data.  Without this dns_resolver_instantiate() will return
      -EINVAL and the key will not be instantiated such that it can be read.
      
      The oops looks like:

      libceph: retry after authorization failure · 692d20f5
      Sage Weil authored
      
      
      If we mark the connection CLOSED we will give up trying to reconnect to
      this server instance.  That is appropriate for things like a protocol
      version mismatch that won't change until the server is restarted, at which
      point we'll get a new addr and reconnect.  An authorization failure like
      this is probably due to the server not properly rotating it's secret keys,
      however, and should be treated as transient so that the normal backoff and
      retry behavior kicks in.

      get_user_pages() can return fewer pages than we ask for.  We were returning
      a bogus pointer/error code in that case.  Instead, loop until we get all
      the pages we want or get an error we can return to the caller.
