Testing like this for TP_STATUS_AVAILABLE clearly is a stupid bug since it always returns true.

The test currently runs for ... TPACKET_V1: RX_RING, TX_RING TPACKET_V2: RX_RING, TX_RING TPACKET_V3: RX_RING ... and will output on success: test: TPACKET_V1 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V1 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V3 with PACKET_RX_RING .................... 100 pkts (9600 bytes) OK.

Changes: v3->v2: rebase (no other changes) passes selftest v2->v1: read f->num_members only once fix bug: test rollover mode + flag Minimize packet drop in a fanout group. If one socket is full, roll over packets to another from the group. Maintain flow affinity during normal load using an rxhash fanout policy, while dispersing unexpected traffic storms that hit a single cpu, such as spoofed-source DoS flows. Rollover breaks affinity for flows arriving at saturated sockets during those conditions. The patch adds a fanout policy ROLLOVER that rotates between sockets, filling each socket before moving to the next. It also adds a fanout flag ROLLOVER. If passed along with any other fanout policy, the primary policy is applied until the chosen socket is full. Then, rollover selects another socket, to delay packet drop until the entire system is saturated. Probing sockets is not free. Selecting the last used socket, as rollover does, is a greedy approach that maximizes chance of success, at the cost of extreme load imbalance. In practice, with sufficiently long queues to absorb bursts, sockets are drained in parallel and load balance looks uniform in `top`. To avoid contention, scales counters with number of sockets and accesses them lockfree. Values are bounds checked to ensure correctness. Tested using an application with 9 threads pinned to CPUs, one socket per thread and sufficient busywork per packet operation to limits each thread to handling 32 Kpps. When sent 500 Kpps single UDP stream packets, a FANOUT_CPU setup processes 32 Kpps in total without this patch, 270 Kpps with the patch. Tested with read() and with a packet ring (V1). Also, passes psock_fanout.c unit test added to selftests. Signed-off-by: NWillem de Bruijn <willemb@google.com> Reviewed-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.

To save connecting and searching for a given grub menu for each test, ktest.pl will cache the grub number it found. The problem is that different tests might use a different grub menu, but ktest.pl will ignore it. Instead, have ktest.pl check if the grub menu it used to cache the content is the same as when it grabbed the menu. If not, grab it again, otherwise just return the cached value.

Stricter validation was introduced with commit da27a243 ("efivarfs: guid part of filenames are case-insensitive") and commit 47f531e8 ("efivarfs: Validate filenames much more aggressively"), which is necessary for the guid portion of efivarfs filenames, but we don't need to be so strict with the first part, the variable name. The UEFI specification doesn't impose any constraints on variable names other than they be a NULL-terminated string. The above commits caused a regression that resulted in users seeing the following message, $ sudo mount -v /sys/firmware/efi/efivars mount: Cannot allocate memory whenever pstore EFI variables were present in the variable store, since their variable names failed to pass the following check, /* GUID should be right after the first '-' */ if (s - 1 != strchr(str, '-')) as a typical pstore filename is of the form, dump-type0-10-1-<guid>. The fix is trivial since the guid portion of the filename is GUID_LEN bytes, we can use (len - GUID_LEN) to ensure the '-' character is where we expect it to be. (The bogus ENOMEM error value will be fixed in a separate patch.)

The reboot just wants to get to the next kernel. But if a warning (Call Trace) appears, the monitor will report an error, and the reboot will think something went wrong and power cycle the box, even though we successfully made it to the next kernel.
