r332436: Add the ability to specify absolute and relative offsets to size partitions. To create hybrid boot media we want to specify a partition at a known location. This extends the syntax of size partitions to include an optional offset that can be absolute or relative. It also introduces validation to make sure that this hasn't resulted in overlapping partitions. I haven't added this to the file and process partition specifications yet but the mechanics are designed such that if someone comes up with a good way of specifying the offset it will be fairly easy to add in. r332440: Fix a conditional that got mucked up.

(Previous commit didn't have new files added.) r331949: Add the etdump utility for dumping El Torito boot catalog information. This can be used to check existing images but will be used in the future to find EFI ESP images placed in El Torito catalogs so they can be used for hybrid boot purposes. r332427: Check the return value of fseek. r332438: Remove a debugging printf that crept in.

Don't show the number of currently established SCTP associations, since this is not monotonically increasing. It's number can be derived from the other counters shown.

r330710: tftpd: Flush files as soon as they are fully received On an RRQ, tftpd doesn't exit as soon as it's finished receiving a file. Instead, it waits five seconds just in case the client didn't receive the server's last ACK and decides to resend the final DATA packet. Unfortunately, this created a 5 second delay from when the client thinks it's done sending the file, and when the file is available for other processes. Fix this bug by closing the file as soon as receipt is finished. PR: 157700 Reported by: Barry Mishler r330718: tftpd: Verify world-writability for WRQ when using relative paths tftpd(8) says that files may only be written if they already exist and are publicly writable. tftpd.c verifies that a file is publicly writable if it uses an absolute pathname. However, if the pathname is relative, that check is skipped. Fix it. Note that this is not a security vulnerability, because the transfer ultimately doesn't work unless the file already exists and is owned by user nobody. Also, this bug does not affect the default configuration, because the default uses the "-s" option which makes all pathnames absolute. PR: 226004 r330719: tftpd: Abort on an WRQ access violation On a WRQ (write request) tftpd checks whether the client has access permission for the file in question. If not, then the write is prevented. However, tftpd doesn't reply with an ERROR packet, nor does it abort. Instead, it tries to receive the packet anyway. The symptom is slightly different depending on the nature of the error. If the target file is nonexistent and tftpd lacks permission to create it, then tftpd will willingly receive the file, but not write it anywhere. If the file exists but is not writable, then tftpd will fail to ACK to WRQ. PR: 225996 r330720: tftpd: reject unknown opcodes If tftpd receives a command with an unknown opcode, it simply exits 1. It doesn't send an ERROR packet, and the client will hang waiting for one. Fix it. PR: 226005

tail: fix "tail -r" for piped input that begins with '\n' A subtle logic bug, probably introduced in r311895, caused tail to print the first two lines of piped input in forward order, if the very first character was a newline.
