| * Avoid 64-bit "switch()" statements on 32-bit architecturesLinus Torvalds2009-03-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ee6f779b9e0851e2f7da292a9f58e0095edf615a ("filp->f_pos not correctly updated in proc_task_readdir") changed the proc code to use filp->f_pos directly, rather than through a temporary variable. In the process, that caused the operations to be done on the full 64 bits, even though the offset is never that big. That's all fine and dandy per se, but for some unfathomable reason gcc generates absolutely horrid code when using 64-bit values in switch() statements. To the point of actually calling out to gcc helper functions like __cmpdi2 rather than just doing the trivial comparisons directly the way gcc does for normal compares. At which point we get link failures, because we really don't want to support that kind of crazy code. Fix this by just casting the f_pos value to "unsigned long", which is plenty big enough for /proc, and avoids the gcc code generation issue.

| | * dm crypt: fix kcryptd_async_done parameterHuang Ying2009-03-161-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the async encryption-complete function (kcryptd_async_done), the crypto_async_request passed in may be different from the one passed to crypto_ablkcipher_encrypt/decrypt. Only crypto_async_request->data is guaranteed to be same as the one passed in. The current kcryptd_async_done uses the passed-in crypto_async_request directly which may cause the AES-NI-based AES algorithm implementation to panic. This patch fixes this bug by only using crypto_async_request->data, which points to dm_crypt_request, the crypto_async_request passed in. The original data (convert_context) is gotten from dm_crypt_request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When renaming a mapped device validate the length of the new name. The rename ioctl accepted any correctly-terminated string enclosed within the data passed from userspace. The other ioctls enforce a size limit of DM_NAME_LEN. If the name is changed and becomes longer than that, the device can no longer be addressed by name. Fix it by properly checking for device name length (including terminating zero).

| * | Fast TSC calibration: calculate proper frequency error boundsLinus Torvalds2009-03-171-45/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for ntpd to correctly synchronize the clocks, the frequency of the system clock must not be off by more than 500 ppm (or, put another way, 1:2000), or ntpd will end up giving up on trying to synchronize properly, and ends up reseting the clock in jumps instead. The fast TSC PIT calibration sometimes failed this test - it was assuming that the PIT reads always took about one microsecond each (2us for the two reads to get a 16-bit timer), and that calibrating TSC to the PIT over 15ms should thus be sufficient to get much closer than 500ppm (max 2us error on both sides giving 4us over 15ms: a 270 ppm error value). However, that assumption does not always hold: apparently some hardware is either very much slower at reading the PIT registers, or there was other noise causing at least one machine to get 700+ ppm errors. So instead of using a fixed 15ms timing loop, this changes the fast PIT calibration to read the TSC delta over the individual PIT timer reads, and use the result to calculate the error bars on the PIT read timing properly. We then successfully calibrate the TSC only if the maximum error bars fall below 500ppm. In the process, we also relax the timing to allow up to 25ms for the calibration, although it can happen much faster depending on hardware.

| * | Fix potential fast PIT TSC calibration startup glitchLinus Torvalds2009-03-171-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During bootup, when we reprogram the PIT (programmable interval timer) to start counting down from 0xffff in order to use it for the fast TSC calibration, we should also make sure to delay a bit afterwards to allow the PIT hardware to actually start counting with the new value. That will happens at the next CLK pulse (1.193182 MHz), so the easiest way to do that is to just wait at least one microsecond after programming the new PIT counter value. We do that by just reading the counter value back once - which will take about 2us on PC hardware.

This isn't a problem on ifconfig up, as ->set_rx_mode() will be called shortly afterwards which will program the filters again, but it does trigger when changing the MTU, which calls mv643xx_eth_stop() and then mv643xx_eth_open() by hand to repopulate the receive rings with skbuffs of the new size. Swap the initialisation of the PORT_START register and the call to the unicast filter setup function to fix this. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: David S.
