[Bug 1398569] Re: schroot overlay v2 support
I'm glad to see this was already fixed almost a year ago, but the version of schroot that is available in 14.04.3 with kernel 3.19.0-25-generic (schroot 1.6.8-1ubuntu1) is broken without it. Is there a plan to push 1.6.10-1ubuntu1 to at least trusty-backports maybe? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1398569 Title: schroot overlay v2 support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/schroot/+bug/1398569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1222912] Re: Error parsing proxy.pac
A real oddity to me is that if I put the plugin into debug mode before
running firefox it all works:
$ export ICEDTEAPLUGIN_DEBUG=true
$ firefox --new-instance 2>&1 | tee /tmp/ffdebug.log
(will attach log momentarily)
after downloading the source package and poking around, I found this
code:
gchar* proxy;
uint32_t len;
gchar* decoded_url = (gchar*) calloc(strlen(parts[4]) + 1,
sizeof(gchar));
IcedTeaPluginUtilities::decodeURL(parts[4], _url);
PLUGIN_DEBUG("parts[0]=%s, parts[1]=%s, reference, parts[3]=%s,
parts[4]=%s -- decoded_url=%s\n", parts[0], parts[1], parts[3], parts[4],
decoded_url);
gchar* proxy_info;
#if MOZILLA_VERSION_COLLAPSED < 1090100
proxy = (char*) malloc(sizeof(char)*2048);
#endif
proxy_info = g_strconcat ("plugin PluginProxyInfo reference ",
parts[3], " ", NULL);
if (get_proxy_info(decoded_url, , ) == NPERR_NO_ERROR)
{
proxy_info = g_strconcat (proxy_info, proxy, NULL);
}
PLUGIN_DEBUG("Proxy info: %s\n", proxy_info);
plugin_send_message_to_appletviewer(proxy_info);
g_free(decoded_url);
decoded_url = NULL;
g_free(proxy_info);
proxy_info = NULL;
#if MOZILLA_VERSION_COLLAPSED < 1090100
g_free(proxy);
proxy = NULL;
#endif
note that proxy is only allocated if MOZILLA_VERSION_COLLAPSED < 1090100
(is not even initialized otherwise), but is used if get_proxy_info
succeeds, so on the first invocation we get (potentially) garbage output
like so:
plugin PluginProxyInfo reference 0 �Þ
for whatever reason, having debugging enabled causes this not to happen
(perhaps a side-effect of the fprintf call inside the PLUGIN_DEBUG
macro? I'm not really sure)
Anyway, I am building a possible patch for this right now and will
submit once I have verified that it works as I expect it to.

[Bug 1222912] Re: Error parsing proxy.pac
Looks like that was actually only about 95% of the way to the bug. Here's the real issue, one call further in, in the get_proxy_info function: gpointer instance=getFirstInTableInstance(instance_to_id_map); browser_functions.getvalueforurl((NPP) instance, NPNURLVProxy, siteAddr, proxy, len); looking at the docs for that function (NPN_GetValueForURL), the signature is: NPError NPN_GetValueForURL(NPP instance, NPNURLVariable variable, const char *url, char **value, uint32_t *len); and an important point called out for the value parameter: *Note: the value may have internal NULL bytes and may not be NULL- terminated.* importantly, neither the return value nor len are actually checked before moving on and attempting to use the value. When Firefox is set to use a PAC file that doesn't exist, the function call fails, no allocation happens for **value (leaving whatever garbage was in memory before), len is set to 0, but IcedTea disregards that and continues on as though it succeeded, and concatenates random memory garbage to the plugin PluginProxyInfo string that is to be sent over to the java process. Back in the previous function call, it is enough to work around the bug by changing gchar* proxy; to gchar* proxy = NULL;, but it is perhaps only partially correct. Attached here is a patch that resolves the issue in my case. ** Patch added: "fix_invalid_byte_sequence.patch" https://bugs.launchpad.net/ubuntu/+source/icedtea-web/+bug/1222912/+attachment/4473859/+files/fix_invalid_byte_sequence.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1222912 Title: Error parsing proxy.pac To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/icedtea-web/+bug/1222912/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1222912] Re: Error parsing proxy.pac
I'm having a very similar issue here. If I tell Firefox to use a proxy file (i.e. set network.proxy.autoconfig_url = file:///etc/proxy.pac and network.proxy.type = 2), and that pacfile exists, everything works fine, even if returning two proxies. If I then rename or remove that proxy.pac, firefox goes along on its way merrily, but the IcedTea plugin fails. Running firefox from the cli yields the following output: java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.12.04.1) OpenJDK Client VM (build 24.79-b02, mixed mode, sharing) Unable to use Firefox's proxy settings.

[Bug 1251580] Re: 8086:0152 [Dell OptiPlex 9010] Display is heavily distorted after kernel upgrades
I don't actually have direct access to the box in question, unfortunately, and it is a very pared down install (it is at one of our clients' locations, and they are particular enough about their network that I'm not sure the machine in question would even be able to submit that report) I am working on obtaining similar hardware. If I manage to do so, I will be more than happy to submit such a report myself. In the meantime, I will see if I can update the kernel using the same solution Antoine used.

[Bug 1251580] Re: Display is heavily distorted after kernel upgrades
Is there any progress on publishing a fix to this in the lts-trusty HWE for precise (or alternately providing lts-utopic for precise)? This is currently an issue for some systems I am supporting. Downgrading them to a 3.11 kernel or changing distributions is not currently an option for me, and it looks like lts-utopic is not available for precise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1251580 Title: Display is heavily distorted after kernel upgrades To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1251580/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
