The ecryptfs_find_auth_tok_for_sig() call is moved before the
mutex_lock(s->tfm_mutex) instruction in order to avoid possible deadlocks
that may occur by holding the lock on the two semaphores 'key->sem' and
's->tfm_mutex' in reverse order.

Authentication tokens content may change if another requestor calls the
update() method of the corresponding key. The new function
ecryptfs_verify_auth_tok_from_key() retrieves the authentication token from
the provided key and verifies if it is still valid before being used to
encrypt or decrypt an eCryptfs file.

The size of the 'keysig' array is incremented of one byte in order to make
room for the NULL character. The 'keysig' variable is used, in the function
ecryptfs_generate_key_packet_set(), to find an authentication token with
the given signature and is printed a debug message if it cannot be
retrieved.

This patch removes the 'num_global_auth_toks' field of the

the 'global_auth_tok_list' list. This variable is not needed because there
are no checks based upon it.

Unlock the page in error path of ecryptfs_write_begin(). This may

Change the write path to encrypt the data only when the page is written to
disk in ecryptfs_writepage. Previously, ecryptfs encrypts the page in
ecryptfs_write_end which means that if there are multiple write requests to
the same page, ecryptfs ends up re-encrypting that page over and over again.
This patch minimizes the number of encryptions needed.

Now that grow_file() is not called in the ecryptfs_create() path, the
ECRYPTFS_NEW_FILE flag is no longer needed. It helped
ecryptfs_readpage() know not to decrypt zeroes that were read from the
lower file in the grow_file() path.
Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
|
|
When creating a new eCryptfs file, the crypto metadata is written out
and then the lower file was being "grown" with 4 kB of encrypted zeroes.
I suspect that growing the encrypted file was to prevent an information
leak that the unencrypted file was empty. However, the unencrypted file
size is stored, in plaintext, in the metadata so growing the file is
unnecessary.

After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add
support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX,
and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan
acceleration via ethtool set_flags, always return -EINVAL from that
function. Fix by returning -EINVAL only if requested features do not
match current settings and can not be changed by driver.
Change any driver that define ethtool->set_flags to use
ethtool_invalid_flags() to avoid similar problems in the future
(also on drivers that do not have the problem).
Tested with modified (to reproduce this bug) myri10ge driver.

The jme driver uses the legacy PCI power management, so it has to do
some PCI-specific things in its ->suspend() and ->resume() callbacks,
which isn't necessary and should better be done by the PCI
sybsystem-level power management code. It also doesn't use device
wakeup flags correctly.
Convert jme to the new PCI power management framework and make it
let the PCI subsystem take care of all the PCI-specific aspects of
device handling during system power transitions.

Avoid theoretical race condition regarding accessing dev->features
NETIF_F_LRO flag, which is illustrated below.
CPU1 CPU2
myri10ge_clean_rx_done(): myri10ge_set_flags():
or
myri10ge_set_rx_csum():
if (dev->features & NETIF_F_LRO)
setup lro
dev->features |= NETIF_F_LRO
or
dev->features &= ~NETIF_F_LRO;
if (dev->features & NETIF_F_LRO)
flush lro
On the way reduce myri10ge_rx_done() number of arguments and calls by
moving mgp->small_bytes check into that function. That reduce code size
from:
text data bss dec hex filename
36644 248 100 36992 9080 drivers/net/myri10ge/myri10ge.o
to:
text data bss dec hex filename
36037 247 100 36384 8e20 drivers/net/myri10ge/myri10ge.o
on my i686 system, what should also make myri10ge_clean_rx_done()
being faster.

The mac address of the bridge device may be changed when a new interface
is added to the bridge. If this happens, then the bridge needs to call
the network notifiers to tickle any other systems that care. Since bridge
can be a module, this also means exporting the notifier function.

The current handling of echoed IP timestamp options with prespecified
addresses is rather broken since the 2.2.x kernels. As far as i understand
it, it should behave like when originating packets.
Currently it will only timestamp the next free slot if:
- there is space for *two* timestamps
- some random data from the echoed packet taken as an IP is *not* a local IP
This first is caused by an off-by-one error. 'soffset' points to the next
free slot and so we only need to have 'soffset + 7 <= optlen'.
The second bug is using sptr as the start of the option, when it really is
set to 'skb_network_header(skb)'. I just use dptr instead which points to
the timestamp option.
Finally it would only timestamp for non-local IPs, which we shouldn't do.
So instead we exclude all unicast destinations, similar to what we do in
ip_options_compile().

The current SocketCAN implementation for the Bosch c_can cell doesn't
account the TX bytes correctly, because it calls
c_can_inval_msg_object() (which clears the msg ctrl register) before
reading the DLC value:
for (/* nix */; (priv->tx_next - priv->tx_echo) > 0; priv->tx_echo++) {
msg_obj_no = get_tx_echo_msg_obj(priv);
c_can_inval_msg_object(dev, 0, msg_obj_no);
val = c_can_read_reg32(priv, &priv->regs->txrqst1);
if (!(val & (1 << msg_obj_no))) {
can_get_echo_skb(dev,
msg_obj_no - C_CAN_MSG_OBJ_TX_FIRST);
stats->tx_bytes += priv->read_reg(priv,
&priv->regs->ifregs[0].msg_cntrl)
& IF_MCONT_DLC_MASK;
stats->tx_packets++;
}
}
So, we will always read 0 for the DLC value and "ifconfig" will report
*0* TX Bytes.
The fix is quite easy: Just move c_can_inval_msg_object() to the end of
the if() statement. So:
* We only call c_can_inval_msg_object() if the message was
actually transmitted
* We read out the DLC value _before_ clearing the msg ctrl
register

can_ioctl is the only reason for struct proto to be non-const.
script/check-patch.pl suggests struct proto be const.
Setting the reference to the common can_ioctl() in all CAN protocols directly
