The umb(4) driver provides support for USB MBIM (Mobile Broadband
Interface Model) devices.
MBIM devices establish connections via cellular networks such as GPRS,
UMTS, and LTE. They appear as a regular point-to-point network interface, transporting raw IP frames.
Required configuration parameters like PIN and APN have to be set with
umbctl(8), a new tool specific to this driver. The IP address is configured
automatically; the default route and DNS server information have to be set
separately.
The driver is not fully functional yet, it is therefore still marked as
experimental and disabled by default. Any help welcome to complete it!
Tested on NetBSD/amd64, with a Sierra Wireless EM7345 LTE modem on a Lenovo
ThinkPad T440s. No functional change expected otherwise.
be interested in. Let individual commands decide if ioctl(DIOCMWEDGES)
should be done. I was conservative and set the flag on any command
that might create/modify/delete partitions in any way.

Change shifting left 1 to shifting 1U. This corrects the issue.
if (cidr < 32) { /* more than 1 bit in mask */
/* check for non-contig netmask */
if ((mask ^ (((1 << cidr) - 1) << (32 - cidr))) != 0) // <- here
return -1; /* noncontig, no pfxlen */
}

This avoids the stupid null deref I added a couple of commits
ago (on bad usage) and also simplifies the rest of the routine
which no longer needs to check the arg count nearly as much.
Thanks to Alexander Nasonov for finding the null deref bug.
ispell also says that we should s/parseable/parsable/ but I'm
not sure about that one, so I left it.
I also left a correct spelling that no-one has bothered to mangle!
nanoseconds, 9 digits) the kernel happens to send in the timestamps
in log messages.
Output (numeric) timestamps (when produced) are unchanged and always
in microseconds (for now).
- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)
identd has aliasing violations, use -fno-strict-aliasing.
newfs_msdos's getbpbinfo() has missing {} issues.
sysctl's kern_cp_id() has missing {} issues.
convert several raidframe ioctls to be bitsize idempotent so that
they work the same in 32 and 64 bit worlds, allowing netbsd32 to
configure and query raid properly. remove useless 'row' in a few
places. add COMPAT_80 and put the old ioctls there.
raidframeio.h:
RAIDFRAME_TEST_ACC
- remove, unused
RAIDFRAME_GET_COMPONENT_LABEL
- convert to label not pointer to label
RAIDFRAME_CHECK_RECON_STATUS_EXT
RAIDFRAME_CHECK_PARITYREWRITE_STATUS_EXT
RAIDFRAME_CHECK_COPYBACK_STATUS_EXT
- convert to progress info not pointer to info
RAIDFRAME_GET_INFO
- version entirely.
raidframevar.h:
- rf_recon_req{} has row, flags and raidPtr removed (they're
not a useful part of this interface.)
- RF_Config_s{} and RF_DeviceConfig_s{} have numRow/rows removed.
- RF_RaidDisk_s{} is re-ordered slightly to fix alignment
padding - the actual data was already OK.
- InstallSpareTable() loses row argument
rf_compat32.c has code for RF_Config_s{} in 32 bit mode, used
by RAIDFRAME_CONFIGURE and RAIDFRAME_GET_INFO32.
rf_compat80.c has code for rf_recon_req{}, RF_RaidDisk_s{} and
RF_DeviceConfig_s{} to handle RAIDFRAME_FAIL_DISK,
RAIDFRAME_GET_COMPONENT_LABEL, RAIDFRAME_CHECK_RECON_STATUS_EXT,
RAIDFRAME_CHECK_PARITYREWRITE_STATUS_EXT,
RAIDFRAME_CHECK_COPYBACK_STATUS_EXT, RAIDFRAME_GET_INFO.
move several of the per-ioctl code blocks into separate functions.
add rf_recon_req_internal{} to replace old usage of global
rf_recon_req{} that had unused void * in the structure, ruining
it's 32/64 bit ABI.
add missing case for RAIDFRAME_GET_INFO50.
adjust raid tests to use the new .conf format, and add a case to
test the old method as well.
raidctl:
deal with lack of 'row' members in a couple of places.
fail request no longer takes row.
handle "START array" sections with just "numCol numSpare", ie
no "numRow" specified. for now, generate old-style configuration
but update raidctl.8 to specify the new style (keeping reference
to the old style.)
note that: RF_ComponentLabel_s::{row,num_rows} and
RF_SingleComponent_s::row are obsolete but not removed yet.
