2016-07-03ntpd: daemonize before DNS resolutionDenys Vlasenko
This resolves the following use case problem: "I start ntpd by default from /etc/init.d There might be no working network connection (not configured properly for whatever reason, hardware problems, whatelse). With busybox 1.25 ntpd seems to loop forever if now NTP servers are found, blocking the boot process and I never get a login to solve a possible pb or to do a first time configuration."

2016-06-29build system: make CONFIG_FEATURE_USE_BSS_TAIL less funkyDenys Vlasenko
CONFIG_FEATURE_USE_BSS_TAIL code was aliasing bb_common_bufsiz1 to _end. This is unreliable: _end may be not sufficiently aligned. Change code to simply enlarge COMMON_BUFSIZE when we detect that _end has significant amount of space to the end of page. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2016-06-24df: use f_frsize instead of f_bsize for correct sizesNatanael Copa
Use the correct field f_frsize instead of f_bsize. The statfs f_bsize is the "Optimal transfer block size" while the f_frsize is the "Fragment size (since Linux 2.6)". On some FUSE filesystems those may differ.

2016-06-24i2cdump: don't use common_bufsiz1Bartosz Golaszewski
Commit e6a2f4cc changed the way common_bufsiz1 works. Now it needs to be initialized before using, but i2cdump wasn't updated by said patch. Since the fact that we're using common_bufsiz1 here isn't obvious (no G_INIT() macro, no other global variables), drop it and simply allocate the integer array required for block reads on the stack. Tested with i2c block read on a Lenovo Thinkpad laptop. Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2016-06-23ping: populate icmp_id field for "simple" ping tooJonas Danielsson
The ICMP RFC says that identifier and sequence number may be zero. Having them zero for a Echo message, along with a data of zero's as well will result in a Echo reply message with only zero's. Some NAT implementations seem to get the checksum wrong on these packages. Setting a checksum of 0x0 instead of 0xffff. Through NAT: Internet Control Message Protocol Type: 0 (Echo (ping) reply) Code: 0 Checksum: 0x0000 [incorrect, should be 0xffff] Identifier (BE): 0 (0x0000) Identifier (LE): 0 (0x0000) Sequence number (BE): 0 (0x0000) Sequence number (LE): 0 (0x0000) Data (56 bytes) Data: 000000000000000000000000000000000000000000000000... [Length: 56] Without NAT: Internet Control Message Protocol Type: 0 (Echo (ping) reply) Code: 0 Checksum: 0xffff [correct] Identifier (BE): 0 (0x0000) Identifier (LE): 0 (0x0000) Sequence number (BE): 0 (0x0000) Sequence number (LE): 0 (0x0000) [Request frame: 189] [Response time: 0.024 ms] Data (56 bytes) Data: 000000000000000000000000000000000000000000000000... [Length: 56] And this in turn will make some hardware MAC checksum offloading engines drop the packet. (This was seen with a Synopsis MAC, the same one used in for instance the stmmac Ethernet driver in the linux kernel.) This change can be seen as a workaround for bugs in other layers. But just setting an identifier for the Echo message packet will avoid prodding the hornets nest. function old new delta common_ping_main 424 500 +76 Signed-off-by: Jonas Danielsson <jonasdn@axis.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
