exit code not passed if rx pipe fails
by George Coulouris 25 Apr '12

25 Apr '12

Hello, If udp-receiver is writing to a pipe and the pipe fails, udp-receiver will incorrectly exit with a returncode of zero. This is easily tested with a trivial pipe program that copies stdin to stdout, but exits with a nonzero status upon encountering eof. Adding the following to startReceiver() in udpr-negotiate.c is sufficient to fix this behavior: <---- cut here int ret; ... if(pipePid) { ret=udpc_waitForProcess(pipePid, "Pipe"); } ... return ret; <---- cut here Regards, George Coulouris National Center for Biotechnology Information (contractor)

Broadcom BCM57780 network card

Hi all, I have been using Udpcast for a couple of years. This magic tool saved me hundreds hours of tedious work. Thanks a lot! Last week, I got a bunch of 50 new Dell computers I need to clone (Optiplex 3800). Udpcast 20110710 (booted on default CD) recognizes the right Broadcom BCM57780 network card, offers the right tg3 driver, but hangs on the following "No PHY devices" error: <6>tg3.c:v3.117 (January 25, 2011) <6>tg3 0000:02:00.0: found PCI INT A -> IRQ11 <6>tg3 0000:02:00.0: sharing IRQ11 with 0000:00:01.0 <6>tg3 0000:02:00.0: sharing IRQ11 with 0000:00:1b.0 <6>tg3 0000:02:00.0: sharing IRQ11 with 0000:00:1c.0 <6>tg3 0000:02:00.0: sharing IRQ11 with 0000:00:1f.1 <6>tg3 0000:02:00.0: sharing IRQ11 with 0000:01:00.0 <7>tg3 0000:02:00.0: setting latency timer to 64 <6>tg3 mdio bus: probed <4>tg3 0000:02:00.0: No PHY devices <3>tg3 0000:02:00.0: Problem fetching invariants of chip, aborting However, this network card works fine with Ubuntu 10.04.3 as you can see in /var/log/dmesg: [ 2.119312] tg3.c:v3.102 (September 1, 2009) [ 2.119329] tg3 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 2.119338] tg3 0000:02:00.0: setting latency timer to 64 [ 2.133374] tg3 mdio bus: probed [ 2.152912] eth0: Tigon3 [partno(BCM57780) rev 57780001] (PCI Express) MAC address bc:30:5b:ca:84:cc [ 2.152915] eth0: attached PHY driver [Broadcom BCM57780] (mii_bus:phy_addr=200:01) [ 2.152917] eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1] [ 2.152918] eth0: dma_rwctrl[76180000] dma_mask[64-bit] How could I get an udpacst.iso file which would be usable on these PCs? Is it just a question of network module paramter I should add or is it more complicated? (I am not very familiar with kernel compilation etc.). Thanks again. Bertrand THOMAS PS Sorry if this question has already been asked, but I couldn't reach the archive server at https://udpcast.linux.lu/pipermail/udpcast/.
