* amd64 pmap: reorder IPI send and local TLB flush in TLB invalidations.Konstantin Belousov2020-06-105-57/+127
| | | | | | | | | | | | | | | | | | | | | | | | Right now code first flushes all local TLB entries that needs to be flushed, then signals IPI to remote cores, and then waits for acknowledgements while spinning idle. In the VMWare article 'Don’t shoot down TLB shootdowns!' it was noted that the time spent spinning is lost, and can be more usefully used doing local TLB invalidation. We could use the same invalidation handler for local TLB as for remote, but typically for pmap == curpmap we can use INVLPG for locals instead of INVPCID on remotes, since we cannot control context switches on them. Due to that, keep the local code and provide the callbacks to be called from smp_targeted_tlb_shootdown() after IPIs are fired but before spin wait starts.

* Adjust crypto_apply function callbacks for OCF.John Baldwin2020-06-1022-141/+185
| | | | | | | | | | | | | | | | | | | | | | | | | | | - crypto_apply() is only used for reading a buffer to compute a digest, so change the data pointer to a const pointer. - To better match m_apply(), change the data pointer type to void * and the length from uint16_t to u_int. The length field in particular matters as none of the apply logic was splitting requests larger than UINT16_MAX. - Adjust the auth_xform Update callback to match the function prototype passed to crypto_apply() and crypto_apply_buf(). This removes the needs for casts when using the Update callback. - Change the Reinit and Setkey callbacks to also use a u_int length instead of uint16_t. - Update auth transforms for the changes. While here, use C99 initializers for auth_hash structures and avoid casts on callbacks.

* pci: loosen PCIe hot-plug requirementsChuck Tuffli2020-06-101-9/+1
| | | | | | | | | | | | | | | | | | | | | The original PCIe hot-plug code required a couple of things which cause PCI probing errors on the QEMU Q35 system and possibly physical systems (Dell R6515). Allocate the hot-plug interrupt as shared to support INTx interrupts. The hot-plug interrupt mechanism should normally be MSI as PCIe mandates MSI support, but QEMU's Q35 bridge only provides INTx interrupts. Second, the code required the Electromechanical Interlock (Slot Status EIS) to be engaged if present (Slot Capability EIP). Some platforms including QEMU Q35 set EIP but not EIS. Fix by deleting the check. Reviewed by: imp, mav, jhb MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D24877 Notes: svn path=/head/; revision=362027

* Prevent TCP Cubic to abruptly increase cwnd after app-limitedRichard Scheffenegger2020-06-101-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cubic calculates the new cwnd based on absolute time elapsed since the start of an epoch. A cubic epoch is started on congestion events, or once the congestion avoidance phase is started, after slow-start has completed. When a sender is application limited for an extended amount of time and subsequently a larger volume of data becomes ready for sending, Cubic recalculates cwnd with a lingering cubic epoch. This recalculation of the cwnd can induce a massive increase in cwnd, causing a burst of data to be sent at line rate by the sender. This adds a flag to reset the cubic epoch once a session transitions from app-limited to cwnd-limited to prevent the above effect.

* execvPe: obviate the need for potentially large stack allocationsKyle Evans2020-06-102-21/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some environments in which execvPe may be called have a limited amount of stack available. Currently, it avoidably allocates a segment on the stack large enough to hold PATH so that it may be mutated and use strsep() for easy parsing. This logic is now rewritten to just operate on the immutable string passed in and do the necessary math to extract individual paths, since it will be copying out those segments to another buffer anyways and piecing them together with the name for a full path. Additional size is also needed for the stack in posix_spawnp(), because it may need to push all of argv to the stack and rebuild the command with sh in front of it. We'll make sure it's properly aligned for the new thread, but future work should likely make rfork_thread a little easier to use by ensuring proper alignment. Some trivial cleanup has been done with a couple of error writes, moving strings into char arrays for use with the less fragile sizeof().

* execvp: fix up the ENOEXEC fallbackKyle Evans2020-06-103-4/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If execve fails with ENOEXEC, execvp is expected to rebuild the command with /bin/sh instead and try again. The previous version did this, but overlooked two details: argv[0] can conceivably be NULL, in which case memp would never get terminated. We must allocate no less than three * sizeof(char *) so we can properly terminate at all times. For the non-NULL argv standard case, we count all the non-NULL elements and actually skip the first argument, so we end up capturing the NULL terminator in our bcopy(). The second detail is that the spec is actually worded such that we should have been preserving argv[0] as passed to execvp: "[...] executed command shall be as if the process invoked the sh utility using execl() as follows: execl(<shell path>, arg0, file, arg1, ..., (char *)0); where <shell path> is an unspecified pathname for the sh utility, file is the process image file, and for execvp(), where arg0, arg1, and so on correspond to the values passed to execvp() in argv[0], argv[1], and so on." So we make this change at this time as well, while we're already touching it. We decidedly can't preserve a NULL argv[0] as this would be incredibly, incredibly fragile, so we retain our legacy behavior of using "sh" for argv[] in this specific instance. Some light tests are added to try and detect some components of handling the ENOEXEC fallback; posix_spawnp_enoexec_fallback_null_argv0 is likely not 100% reliable, but it at least won't raise false-alarms and it did result in useful failures with pre-change libc on my machine.
