Where we piggybacked others, use a separate line to make things clear. 2. Use "Netflix, Inc." everywhere. 3. Use a single line for the copyright for grep friendliness. 4.

* Create a function to translate UEFI paths to unix pathsWarner Losh2017-12-024-3/+733
| | | | | | | | | | | | | | | | | | | | efivar_device_path_to_unix_path translates from UEFI to Unix efivar_unix_path_to_device_path translates from Unix to UEFI At present, only HD() device types are supported (both GPT and MBR). CdRom and floppy devices aren't supported. ZFS isn't supported because there's no way in the UEFI standard to specify a ZFS datastore. Network devices aren't supported either. Three forms of Unix path are accepted: /path/to/file (for a mounted filesystem), //path/to/file (uses the EFI partition on the same disk as /), and dev:/path/to/file (for unmounted filesystem). Two forms are produced (the first and last). Sponsored by: Netflix Notes: svn path=/head/; revision=326458

* Simplify the efivar interface a little.Warner Losh2017-11-102-37/+4
| | | | | | | | | | | | | | | | | | | | We started out having Linux compatible libefivar interfaces. This was in anticipation of porting the GPL'd efibootmgr to FreeBSD via a port. However, since we need that functionality in the base, that port isn't going to happened. It also appears that efivar is a private library that's not used much outside a command line util and efibootmgr. Reduce compatibility with the Linux version a little by removing the mode parameter to efi_set_variable (which was unused on FreeBSD, and not set to something useful in the code we'd written). Also remove some efi error routines that were never implemented and existed only to placate early GPL efibootmgr porting experiments.

| | | | | | | | | | | | | | | | Fix allocating more memory for the names (unlikely to be needed, but still best to get right) to ask for the length the kernel told use we needed, not the old length of the variable. Mind the proper NUL that we add in the space we allocate. Free the old name string before we allcoate a new one to limit what we leak to the last one (free passed in name for the last one in the list), and detect the last one by rv != 0 and errno == ENOENT, rather then just the former to avoid false positives if errno happens to be ENOENT on entry.

| | | | | | | | | | | | efidp_size will return the size, in bytes, of a EFI device path structure. This is a convenience wrapper in the same style as the other linux routines.

* Fix parsing File() nodes in device paths.Warner Losh2017-08-311-11/+8
| | | | | | | | | | | | | | | | | o Add File to the mUefiDevicePathLibDevPathFromTextTable table so we don't include 'File()' in the supposed path name. This happens because of a possible misfeature in the EDK2 code where any path that's not recognized is treated as a File() node. o Convert utf8 input into ucs2 output rather than just copying the utf8 and hoping for the best (no good comes from that). o Remove bogus comment about needing to add 1. The dummy array already is length 1, so that's included in sizeof the struct, so there's no need to add it. Sponsored by: Netflix Notes: svn path=/head/; revision=323057
* Fix printing File() nodes in device paths.Warner Losh2017-08-311-1/+6
| | | | | | | | | | | | Device paths encoded into the FILEPATH_DEVICE_PATH are UCS2 not ASCII/UTF8. Convert to utf8 and print that when printing File paths. Also, since File may be at the end of a long device path, output File() around the path so it doesn't just show up as random nodes that might accidentally match real node paths names and cause errors.

When ported from Tiano core, I commented this out with an ifdef. That was in error because we're supposed to fallback to a filepath when nothing else patches. Instead, restore the original code, but fix DevPathFromTextFilePath to cope with the conversion to narrow strings. Also, fix the off-by-one error in the size of the memory it allocates.

| | | | | | | | | | | | | | | | | | | | | | | | Paper over a coverity issue: *** CID 1372592: API usage errors (BAD_COMPARE) /lib/libefivar/efivar-dp-parse.c: 2723 in DevPathFromTextiSCSI() Truncating the result of "strcmp" to "unsigned short" may cause it to be misinterpreted as 0. Note that "strcmp" may return an integer besides -1, 0, or 1. We do this by making StrCmp return either 0 or 1 for equal or not-equal. There's a bug in the DevPathFromTextiSCSI cast of the return value and this workaround will fix it without breaking other users of StrCmp (all of which test for == 0). https://bugzilla.tianocore.org/show_bug.cgi?id=440 has been filed upstream to log this issue.

* Bring in EDK2 routines for printing and parsing device paths.Warner Losh2017-03-0912-2/+7672
| | | | | | | | | | | | | | | | | | | This commit implements the (mostly?) Linux compatible efidp_format_device_path and efidp_parse_device_path APIs. These are the only APIs exposed through this library. However, they are built on code from Tianocore's EDK2 MdePkg. They are brought in as new files here for reasons described in FreeBSD-update. Symbol versioning will be introduced to control what's exported from the EDK2 code. Some structural changes may be necessary when we move to sharing with sys/boot/efi.
