| | | | | | | | | | | | | | | | | Don't perform the acpi_DeviceIsPresent() check for PCI-PCI bridges. If we are probing a PCI-PCI bridge it is because we found one by enumerating the devices on a PCI bus, so the bridge is definitely present. A few BIOSes report incorrect status (_STA) for some bridges that claimed they were not present when in fact they were. While here, move this check earlier for Host-PCI bridges so attach fails before doing any work that needs to be torn down.

| | | | | | | | | | | | | | | | When fiddling with options of which registers to copy out for a mailbox command and which registers to copy back in when the command completes, the bits being set need to not only specify what bits you want to add from the default from the table but also what bits you want *subtract* (mask) from the default from the table.

These changers will return an Illegal Request type error if the bits are set. This causes "chio status" to fail. The fix is two-fold. First, for changers that claim to be SCSI-2 or older, don't set the DVCID and CURDATA bits for READ ELEMENT STATUS. For newer changers (SCSI-3 and newer), we default to setting the new bits, but back off and try the READ ELEMENT STATUS without the bits if we get an Illegal Request type error. This has been tested on a Qualstar TLS-8211, which is a SCSI-2 changer that does not support the new bits, and a Spectra T-380, which is a SCSI-3 changer that does support the new bits. In the absence of a SCSI-3 changer that does not support the bits, I tested that with some error injection code. (The SMC spec says that support for CURDATA is mandatory, and DVCID is optional.) scsi_ch.c: Add a new quirk, CH_Q_NO_DVCID that gets set for SCSI-2 and older libraries, or newer libraries that report errors when the DVCID/CURDATA bits are set. In chgetelemstatus(), use the new quirk to determine whether or not to set DVCID and CURDATA. If we get an error with the bits set, back off and try without the bits. Set the quirk flag if the read element status succeeds without the bits set. Increase the READ ELEMENT STATUS timeout to 60 seconds after testing with a Spectra T-380. The previous value was 10 seconds, and too short for the T-380. This may be decreased later after some additional testing and investigation.

| | | | | | | | | | | | | | | | | | | | | | | | | In r227207, to fix the issue with possible NULL inp_socket pointer dereferencing, when checking for SO_REUSEPORT option (and SO_REUSEADDR for multicast), INP_REUSEPORT flag was introduced to cache the socket option. It was decided then that one flag would be enough to cache both SO_REUSEPORT and SO_REUSEADDR: when processing SO_REUSEADDR setsockopt(2), it was checked if it was called for a multicast address and INP_REUSEPORT was set accordingly. Unfortunately that approach does not work when setsockopt(2) is called before binding to a multicast address: the multicast check fails and INP_REUSEPORT is not set. Fix this by adding INP_REUSEADDR flag to unconditionally cache SO_REUSEADDR.

| | | | | | | | | | | | | | | | | | | | - As it turns out, not only MSI-X is broken for devices passed through by VMware up to at least ESXi 5.1. Actually, using INTx in that case instead may still result in interrupt storms, with MSI being the only working option in some configurations. So introduce a PCI_QUIRK_DISABLE_MSIX quirk which only blacklists MSI-X but not also MSI and use it for the VMware PCI-PCI-bridges. Note that, currently, we still assume that if MSI doesn't work, MSI-X won't work either - but that's part of the internal logic and not guaranteed as part of the API contract. While at it, add and employ a pci_has_quirk() helper. Reported and tested by: Paul Bucher - Use NULL instead of 0 for pointers.

| | | | | | | | | | | | | | | | When auto-sizing the buffer cache, limit the amount of physical memory used as the estimation of size, to 16GB. This provides around 100K of buffer headers and corresponding KVA for buffer map at the peak. Sizing the cache larger is not useful, also resulting in the wasting and exhausting of KVA for large machines.

An interface with IFT_BRIDGE is initialized with !ND6_IFF_AUTO_LINKLOCAL && !ND6_IFF_ACCEPT_RTADV regardless of net.inet6.ip6.accept_rtadv and net.inet6.ip6.auto_linklocal. To configure an autoconfigured link-local address (RFC 4862), the following rc.conf(5) configuration can be used: ifconfig_bridge0_ipv6="inet6 auto_linklocal" - if_bridge(4) now removes IPv6 addresses on a member interface to be added when the parent interface or one of the existing member interfaces has an IPv6 address. if_bridge(4) merges each link-local scope zone which the member interfaces form respectively, so it causes address scope violation. Removal of the IPv6 addresses prevents it. - if_lagg(4) now removes IPv6 addresses on a member interfaces unconditionally. - Set reasonable flags to non-IPv6-capable interfaces.

| | | | | | | | | | | | | | | | | | | | | | | A problem with the old NFS client where large writes to large files would sometimes result in a corrupted file was reported via email. This problem appears to have been caused by r251719 (reverting r251719 fixed the problem). Although I have not been able to reproduce this problem, I suspect it is caused by another thread increasing np->n_size after the mtx_unlock(&np->n_mtx) but before the vnode_pager_setsize() call. Since the np->n_mtx mutex serializes updates to np->n_size, doing the vnode_pager_setsize() with the mutex locked appears to avoid the problem. Unfortunately, vnode_pager_setsize() where the new size is smaller, cannot be called with a mutex held. This patch returns the semantics to be close to pre-r251719 such that the call to the vnode_pager_setsize() is only delayed until after the mutex is unlocked when np->n_size is shrinking. Since the file is growing when being written, I believe this will fix the corruption. Tested by: remy.nonnenmacher@activnetworks.com Notes: svn path=/stable/9/; revision=253177
